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.
 Built-in internal RC OSC 8 MHz ----
frequency deviation within ±2%, VDD=1.8V~3.6V, temp= -20 ºC ~70 ºC
 Support 1.5 cycle length instruction (NOP15) to generate IR waveform by software.
 Four reset condition
