Description
The SM59R16A2/SM59R08A2 is a 1T (one machine
cycle per clock) single-chip 8-bit microcontroller. It
has 64K/32K-byte embedded Flash for program, and
executes all ASM51 instructions fully compatible with
MCS-51.
z
SM59R16A2/SM59R08A2 contains 2KB on-chip RAM,
48 GPIOs, 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 SM59R16A2/ SM59R08A2
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.
