Product List
SM79108L25, 25 MHz 8KB internal memory MCU
SM79108C40, 40 MHz 8KB internal memory MCU
Description
The SM79108 series product is an 8 - bit single chip micro
controller with 8 KB flash & 256 bytes RAM embedded. It
has 4-channel, 8-bit ADC function build-in, 1-channel
SPWM and 1-channel PWM build-in and A14(segment) x
4(common) LCD driver. It provides hardware features and
a powerful instruction set necessary to make it a versatile
and cost effective controller for those applications demand
up to 32 I/O pins for PDIP package or up to 36 I/O pins for
PLCC/QFP package, or applications which need up to 64K
byte flash memory for program and/or for data.
To program the flash block, a commercial programmer
is capable to do it.
