Description
The SM5952E series product is an 8 - bit single chip
micro controller with 8KB+4KB flash & 1KB SRAM
embedded. It has In-System Programming (ISP)
function and is a derivative of the 8052 micro controller
family.
SM5952E is a versatile and cost effective controller for
those applications which demand up to 36 I/O pins, or
applications which need up to 8KB+4KB 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.
