SN8P021X/8P011X
SN8P021X/8P011X 8-bit microcontroller
1. GENERAL DESCRIPTION
The SN8P021X/8P011X is an 8-bit micro-controller utilized with CMOS technology fabrication and featured with low power
consumption and high performance by its unique electronic structure. This chip is designed with the excellent IC structure,
including the program memory up to 2K/1K-word OTP ROM, 64 bytes of the data memory, one 8-bit T0 basic timer, one 8-bit
timer/event counter, a watch dog timer, three interrupt sources (T0, TC0, INT0), 13 I/O pins and 8 levels stack buffer. Besides,
the user can choose desired oscillator configurations for the controller. There are three oscillator configurations to select for
generating system clock, including high-performing crystal, ceramic resonator or cost-saving RC.

DESCRIPTION
Port 1.0 ~ Port 1.3 bi-direction pins.
System reset inputs pin. Schmitt trigger structure, active “low”, normal stay to “high”.
During program op-code, this pin be pull to 12.5Vdc to reset internal address counter and to
write data into OTP-ROM.
Power supply input pins.
Port 2.0 ~ Port 2.7 bi-direction pins.
Oscillator input pin.
Oscillator output pin.
Port 0.0 and INT0 trigger pin with schmitt trigger structure.
Note : In order to reduce power consumption, the following procedure must be setup.
a). In the SN8P0211/8P0111 version, P1.2 ~ P1.3 must be programmed to input mode with pull up resistor.
