APG221 - 8-bit CMOS Microcontroller

APG221 is an 8051 Compatible high performance 8-bit microcontroller. It integrates advanced digital and analog peripherals to suit for a variety of applications. For digital peripherals, it supports a variety of digital interfaces including UART, SPI, IIS and four timers, integrates an USB 2.0 full speed Host/Device controller and SD card host controller. For analog peripherals, it integrates RC OSC, 16-bit stereo DAC, 16-bit sigma delta ADC, 6 channels 10-bit SAR ADC, PLL, LVD, XOSC and LDO. The microcontroller employs an advanced architecture and compatible with standard 8051 with throughput up to 48 MIPS. All instructions are single-cycled except program branching.

APG221 has 64K bytes program Flash memory, 8K bytes data RAM and 416K bytes data Flash memory storage. The USB 2.0 Host/Device controller FIFO is shared with RAM. It supports USB2.0 full speed. Flexible I/O with different programmable configurations like pull-up, pull-down or wake-up allows APG221 to serve for different I/O requirements in the market.

Three low power saving modes is available: IDLE mode, HOLD mode and SLEEP mode to reduce power consumption for portable device applications.
