1 PRODUCT OVERVIEW
1.1 Description
AX2210 is an 8051 Compatible high performance mixed signal 8-bit microcontroller. It integrates
advanced digital and analog peripherals to s it for a variety of applications. For digital peripherals, it
s pports a variety of digital interfaces incl ding UART, EMI SPI and fo r timers, integrates an USB
2.0 f ll speed Host/Device controller and a MP3 Decoder/Encoder Engine, etc. For analog
peripherals, it integrates RCOSC, DAC, ADC, PLL, LVD, XOSC and LDO. The microcontroller
employs an advanced architect re and compatible with standard 8051 with thro ghp t p to 48
MIPS. All instr ctions are single-cycled except program branching.
The MP3 Decoder Engine can decode MPEG-1, MPEG-2, MPEG-2.5 A dio Layer 1, 2, 3 decoder
nder 24 MHz.
AX2210 has 48K-byte (24K x 16) IROM, 32K-byte OTP (32K x 8), 16K-byte (8K x 16) IRAM, 8K-
byte (4Kx16) RAM2 and 3936 x 24-bit Decode RAM (DECRAM) for MP3 decoder. IROM, IRAM and
part of DECRAM can be sed as program memory. Part of IROM, DECRAM and IRAM can be sed
as data memory.
The USB 2.0 Host/Device controller FIFO is shared with IRAM. It s pports USB2.0 f ll speed.
Flexible I/O with different programmable capabilities like p ll- p, p ll-down or wake- p allows
AX2210 to s it different I/O req irements in the market.
In order to s pport portable applications and red ce power cons mption, three low-power saving
modes are added: IDLE mode, HOLD mode and SLEEP mode.
