SN8P1602B
8-Bit Micro-Controller
1PRODUCT OVERVIEW
GENERAL DESCRIPTION
The SN8P1602B is an 8-bit micro-controller utilized CMOS technology and featured with low power consumption and
high performance by its unique electronic structure.
SN8P1602B is designed with the excellent IC structure including the program memory up to 1K-word OTP ROM, data
memory of 48-bytes RAM, one 8-bit timer (TC0), a watchdog timer, two interrupt sources (TC0, INT0), and 4-level
stack buffers. Besides, user can choose desired oscillator configuration for the controller. There are four external
oscillator configurations to select for generating system clock, including High/Low speed crystal, ceramic resonator or
cost-saving RC. SN8P1602B also includes an internal RC oscillator for slow mode controlled by programming.
