Description
The SM59R16A5 is a 1T (one machine cycle per clock)
single-chip 8-bit microcontroller. It has 64K-byte
embedded Flash for program, and executes all ASM51
instructions fully compatible with MCS-51.
SM59R16A5 contains 2KB on-chip RAM, more than 46
GPIOs (LQFP-48 package type), various serial interfaces
and many peripheral functions as described below. It can
be programmed via writers. Its on-chip ICE is convenient
for users in verification during development stage.
The high performance of SM59R16A5 can achieve
complicated manipulation within short time. About one
third of the instructions are pure 1T, and the average
speed is 8 times of traditional 8051, the fastest one
among all the 1T 51-series.Its excellent EMI and ESD
characteristics are advantageous for many different
applications.
