1. General Descriptions

The AD009-041 a high-performance 4-bit RISC micro-controller embedded up to 2KX12 bits OTP, 32X4

bits SRAM, 10 Input/Output pins, one input pin and built-in one IR LED drive pin. it’s flexible and costeffective

solution for remote control of TV, Fans, Air conditioners ... etc.

2. Features

? MCU Operating voltage: 1.8V to 3.6V

? Operation frequency: MCU run 2 MIPS

? Memory Size

? Program ROM size: 2K X12 bits (OTP type)

SRAM size: 32x4 bits

? Wake up function for power-down mode

? HALT mode wake up source: RTC timer overflow or PA0~3, PB0~3 and PD0~3 edge trigger.

? Provided 10 input /output pins: each I/O has bit programmable as input or output port, these 10 I/Os

also provided edge trigger wake up function and pull up resistors configured by registers.

(a) They are provided with high sink current 20mA @VDD=3V, VOL=0.5V.

(b) They are provided with drive current 7mA @VDD=3V, VOH=2.5V.

(c) Pull up 150k ohm resistor.

? Provide 1 input pin (PA3) shared with VPP pin, pull up 150k ohm resistor and edge trigger wake up

function.

? Built-in one IR LED drive pin.

( Sink current : IOL=210mA at VDD=3V and VOL=0.3V )

? One 8 bits timer, clock source of timer is FMCK /8192( or 4096,2048,1024 ), the content of timer can be

cleared and read by program.
