Description
The SM59A16U1 is a 1T (one machine cycle per clock)
single-chip 8-bit microcontroller. It has 64KB embedded
Flash for program, and executes all ASM51 instructions
fully compatible with MCS-51.
SM59A16U1 contains 6K+256B on-chip RAM, up to 38
GPIOs (48L 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 SM59A16U1 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.
The SM59A16U1 offers outstanding features, like USB
Interface, high performance PWM for motor control
applications, high speed 10-bit A/D convert for barcode
reader applications. The SM59A16U all features as
below.
