Description
The SM59R04A2 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.
SM59R04A2 contains 1KB on-chip RAM, more than 44
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 SM59R04A2 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.
