Description
1T/2T can be switched on the fly
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.
Dual 16-bit Data Pointers (DPTR0 & DPTR1)
38 GPIOs (LQFP 48), GPIOs can select four
types (quasi-bidirectional, push-pull, open
drain, input-only),default is quasi-
bidirectional(pull-up)
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.
Clock & Power
-
-
Operating Voltage: 2.2V ~ 5.5V.
Support Xtal, Internal RC Oscillator
(22.1184MHz, 20KHz) and PLL to user select.
High speed architecture of 1 clock/machine
cycle (1T), runs up to 25MHz
-
-
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.
Power management unit for idle and power
down modes.
Memory.
-
-
64KBytes on-chip flash program memory.
On–chip flash memories support ISP/IAP/ICP
and EEPROM functions.
-
-
-
ISP service program space configurable in
N*256 byte (N=0 to 16) size.
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.
