IS31SE5110 is a general-purpose micro-controller
with 32K embedded flash memory and 1K SRAM.
The CPU is based on 1-T 8051 with T0/T1/T2 and
additional 16-bit T3/T4, 24-bit T5 and a 30-bit WDT.
Embedded in the CPU core are also a full-duplex
UART port, an enhanced EUART port with LIN
capability, one I2C master/slave and two I2C pure
slave controllers, one SPI mater/slave controller, up
to 20 GPIO pins with each GPIO pin configurable as
external interrupt and wake up.
The flexibility in clock setting includes an on-chip
16MHz precision oscillator with the accuracy deviation
of +/-2%, or a low power internal 32kHz oscillator. The
clock selections are combined with flexible power
management schemes, including NORMAL, PMM,
IDLE, and STOP, and SLEEP modes to balance CPU
speed and power consumption.
A Programmable Counter Array (PCA) with 6
channels of Capture/Compare/PWM modules can be
used for various purposes controlling external
devices. There are additional 2 independent 8-bit
PWM and a buzzer waveform generator with
frequency range of 128Hz to 2048Hz and
programmable duty cycle.
Other digital peripherals include a EUART2 with 16-
byte FIFO, which support full LIN protocols, and an
I2C slave controller, and a SPI Master/Slave
controller with 4-byte FIFO.
Analog peripherals include a high performance 12-
bit Analog to Digital Converter (ADC) with 30µs
conversion time and a Programmable Gain Amplifier
as ADC front-end. There are an on-chip temperature
sensor, and a calibrated voltage reference within the
ADC block. A 10-bit voltage output Digital to Analog
Converter (DAC) is also included.
IS31SE5110 also provides a flexible means of flash
programming that supports ISP and IAP. The
protection of data loss is implemented in hardware
by access restriction of critical storage segments.
The code security is reinforced with sophisticated
writer commands and ISP commands. The on-chip
break point processor also allows easy debugging
which can be integrated with ISP. Reliable power-
on-reset circuit and low supply voltage detection
allows reliable operations under harsh environments.
