Description
The SM39R16A2 is a 1T (one machine cycle per clock)
single-chip 8-bit microcontroller. It has 16K-byte
embedded Flash for program, and executes all ASM51
instructions fully compatible with MCS-51.
SM39R16A2 contains 256B on-chip RAM, more than 26
GPIOs (28L package), 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 SM39R16A2 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.
