Acroview, a leader in chip programming, has announced the further expansion of its compatible chip model coverage alongside the release of a new version of its programming software. The company’s core product—the universal programming platform AP8000—has now achieved full adaptation for Analog Devices’ analog microcontroller ADUCM361BCPZ128.

The ADUCM361BCPZ128 is a fully integrated 24-bit data acquisition system with a sampling rate of 3.9 kSPS. It integrates on a single chip dual high-performance, multi-channel Σ-Δ analog-to-digital converters (ADCs), a 32-bit ARM Cortex™-M3 processor, and Flash/EE memory. The chip is designed for direct interface applications with high-precision external sensors in wired and battery-powered applications.

The ADUCM361BCPZ128 includes all the features of the ADuCM360, but integrates only one 24-bit Σ-Δ ADC (ADC1).

The ADUCM361BCPZ128 integrates an on-chip 32 kHz oscillator and a 16 MHz internal high-frequency oscillator. The high-frequency clock, after passing through a programmable divider, provides the operating clock for the processor core. The maximum core clock frequency is 16 MHz, which is not limited by operating voltage or temperature. The microcontroller core is a low-power ARM Cortex-M3 32-bit RISC processor with peak performance of 20 MIPS. The Cortex-M3 integrates a flexible 11-channel DMA controller supporting wired communication peripherals such as SPI, UART, and I²C. The chip also integrates 128 kB of non-volatile Flash/EE memory and 8 kB of SRAM. The analog subsystem includes dual ADCs, each connected to a flexible input multiplexer supporting fully differential and single-ended modes. Other on-chip ADC functions include dual programmable excitation current sources, a diagnostic current source, an AVDD_REG/2 (900 mV) bias voltage generator (for setting the common-mode voltage of the input channel), and a built-in low-side internal ground switch that can turn off external circuits (such as bridge circuits) between conversions.

The ADC integrates two parallel filters: a sinc3 or sinc4 filter operating in parallel with a sinc2 filter. The sinc3/sinc4 filter is used for high-precision measurements, while the sinc2 filter is used for fast measurements and input signal step change detection.

The chip includes a low-noise, low-drift on-chip bandgap reference. It can also be configured to accept one or two external references to support ratiometric measurement mode, with on-chip external reference input buffer options. It also integrates a single-channel buffered voltage output DAC.

The ADUCM361BCPZ128 integrates a rich set of on-chip peripherals that can be configured via microcontroller software as needed, including UART, I²C, dual SPI serial communication interfaces, a 19-pin GPIO port, two general-purpose timers, a wake-up timer, a system watchdog timer, and a 16-bit PWM controller with six output channels.

The ADUCM361BCPZ128 is designed for low-power, battery-critical applications. The microcontroller core consumes 290 μA/MHz in normal operating mode (including Flash/SRAM current). With both ADCs on (input buffers off), PGA gain of 4, one SPI port, and all timers active, total system current can be as low as 1 mA.

The ADUCM361BCPZ128 supports multiple programmable low-power operating modes, including a sleep mode (with internal wake-up timer active) consuming only 4 µA. In sleep mode, the chip can be woken by an external interrupt or the internal wake-up timer, enabling ultra-low-power operation while responding to asynchronous external or periodic events. On-chip factory firmware supports in-circuit serial download via the serial wire interface (2-wire JTAG) and UART, as well as non-intrusive emulation via the serial wire interface. These features are integrated into the low-cost QuickStart™ development system, suitable for this family of high-precision analog microcontrollers.

The ADUCM361BCPZ128 operates from an external 1.8 V to 3.6 V power supply and has an industrial temperature range of −40°C to +125°C.

The AP8000 universal programmer independently developed by Acroview has become a benchmark professional programming solution in the industry. The device supports flexible one-to-one and one-to-eight configuration modes and provides both online and offline operation modes. It has developed dedicated programming solutions for memory chips such as eMMC and UFS, fully covering offline and on-board programming needs for Analog Devices’ full range of chips. The AP8000 adopts an innovative modular design of three core modules—main unit, baseboard, and adapter—giving the device excellent compatibility and expandability. As a universal programming platform, it not only adapts to various programmable chips on the market but also serves as the core component of Acroview’s automated batch programming system IPS5800S with stable and efficient performance, efficiently handling large-scale chip programming tasks to meet mass production demands.

The AP8000 main unit offers flexible connectivity with both USB and NET interfaces, enabling convenient networking of multiple programmers. Through networking, users can easily achieve synchronized control of multiple programmers for efficient parallel programming operations. In terms of safety, the main unit includes intelligent safety protection circuitry that monitors chip placement and circuit connections in real time. If abnormalities such as reverse insertion or short circuits are detected, it immediately triggers a power-off protection mechanism, fully safeguarding the safe operation of both the chip and the programmer. The main unit houses a high-speed FPGA chip, significantly improving data transmission and processing efficiency to ensure a smooth and efficient programming process. To enhance ease of use, an SD card slot is provided on the back of the main unit. Users can store project files generated on a PC to an SD card, insert it into the slot, and then use the programmer’s physical buttons to select, load, and execute programming operations, enabling standalone operation without a PC. This design not only reduces dependence on computer hardware specifications but also simplifies the working environment setup, significantly improving operational flexibility.

In terms of expandability and compatibility, the AP8000 uses a modular combination of baseboard and adapter board to effectively extend the main unit’s functional boundaries. Currently, the device supports products from all major semiconductor manufacturers, covering well-known brands such as SK Hynix, Micron, SANDISK, ASR, and Kingston.
