Description
The SM59R02G1 is a 1T (one machine cycle per clock)
single-chip 8-bit microcontroller. It has 8K-byte
embedded Flash for program, and executes all ASM51
instructions fully compatible with MCS-51.
SM59R02G1 contains 256B on-chip RAM, more than 42
GPIOs (PLCC 44, QFP 44 and LQFP 48), 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 SM59R02G1 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.
