HS2303-P product is an 8-bit MCU manufactured by low consumption and high speed CMOS process, It contains a 1K*14-bit one-time programmable read-only memory (OTP-ROM), There are 14 configuration bits to satisfy the user's requirements, where a bit can be used to prevent the program from being read. HS2303-P provides users with a convenient environment to develop and verify their programs. Conversion can be done with a homemade compiler. 

Wide operating voltage range: 2.0V~3.6V.

Operating temperature range: 0℃~80℃.

Operating frequency range: built-in RC 4MHz±2%.

Low power consumption: 1uA in sleep mode.

1K*14 bit on-chip ROM.

A safe bit (in the code register) protects the program from being read.

40*8bits in-chip registers(SRAM, General register).

Two groups of bidirectional standard I/O ports.

3-Levels for subroutine nested stack.

Energy-saving mode (SLEEP mode).

Each instruction cycle is two clock cycles, 99.9% of instructions are single cycle  instructions.

T-MODE, up to 117 keys can be formed.

M-MODE, up to 49(6*7+7) keys can be formed.

Can be used as universal MCU.

Not indirectly addressable.

Port low level change wake up and power expansion REM high level wake up.

Optional drive (240mA, 280mA, 340mA).

Save electrolytic capacitor optional.
