SN8P021X/8P011X
SN8P021X/8P011X 8-bit microcontroller
1. GENERAL DESCRIPTION
he SN8P021X/8P011X is an 8-bit micro-controller utilized with CMOS technology fabrication and featured with low power
Tconsumption 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.
