The TMS320F280230PTT microcontroller powers the C28x™ core coupled with highly integrated control peripherals in a low pin count device. The code of TMS320F280230PTT is compatible with previous C28x-based codes and provides a high level of analog integration.

An internal voltage regulator allows operation from a single supply rail, an analog comparator with an internal 10-bit reference is added and can be routed directly to control the PWM output, and the ADC operates over a fixed full-scale range of 0 V to 3.3 V conversion operation, and supports ratiometric VREFHI/VREFLO references, and the ADC interface is optimized for low overhead/low latency.

Functional Block Diagram

The AP8000 multi-purpose IC programmer independently developed by Acroview Technology includes three main parts: the host, the base plate, and the adapter seat.

The host supports USB and NET connections, allowing multiple programmers to be networked to achieve the purpose of simultaneously controlling multiple programmers to programmer at the same time. The built-in chip safety protection circuit ensures that even if the chip is reversed or a short circuit caused by other reasons can be detected immediately and the power will be cut off to ensure the safety of the chip and programmer. Embedded high-speed FPGA greatly accelerates data transmission and processing. There is an SD card slot on the back of the main unit. Put the project file produced by the PC software into the root directory of the SD card and insert it into the card slot. The project file can be selected, loaded, and programmed through the buttons on the programmer. command, in order to achieve the purpose of operating without PC, which greatly reduces the cost of PC hardware configuration, and can be conveniently and quickly matched with the working environment.

AP8000 makes the mainframe more expandable by adding an adapter board to the backplane. Currently, it supports devices produced by all mainstream semiconductor manufacturers, including TI, ST, MicroChip, Atmel, Hynix, Macronix, Micron, Samsung, Toshiba, etc. Supported device types include NAND, NOR, MCU, CPLD, FPGA, EMMC, etc., and support file formats including Intel Hex, Motorola S, Binary, POF, etc.
