SM89516L25, 25 MHz 64KB internal memory MCU
SM89516C25, 25 MHz 64KB internal memory MCU
Description
The SM89516 series product is an 8 - bit single chip
micro controller with 64KB flash & 1KB RAM embed-
ded. It is a derivative of the 8052 micro controller family.
With its hardware features and powerful instruction set,
it’s straight forward to make it a versatile and cost effec-
tive 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
64KB 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.
