SM5964C25, 25MHz 64KB internal flash MCU
SM5964C40, 40MHz 64KB internal flash MCU
Description
The SM5964 series product is an 8 - bit single chip
micro controller with 64KB flash & 1K byte RAM
embedded. It has In-System Programming (ISP)
function and is a derivative of the 8052 micro controller
family. It has 5-channel SPWM build-in. With its
hardware features and powerful instruction set, it’s
straight forward to make it a versatile and cost effective
controller for those applications which 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 either for program or for data or
mixed.
To program the on-chip flash memory, a commercial
writer is available to do it in parallel programming
method. The on-chip flash memory can be programmed
in either parallel or serial interface with its ISP feature.
