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.
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.
External RAM addresses up to 64K bytes.
Standard 12T interface for external RAM access.
256 bytes RAM as standard 8052, plus 2K bytes
on-chip expandable RAM
Dual 16-bit Data Pointers (DPTR0 & DPTR1)
Two serial peripheral interfaces in full duplex
mode (UART0 & UART1),
Three 16-bit Timers/Counters. (Timer 0 , 1, 2)
48 GPIOs
External interrupt 0,1 with two priority levels
Programmable watchdog timer (WDT)
One IIC interface (Master/Slave mode)
One SPI interface (Master/Slave mode)
4-channel PWM (12-bit, 10-bit, 8-bit options)
4-channel 16-bit compare /capture /load functions
4-channel 10-bit analog-to-digital converter (ADC)
