8-Bit MCU with 32K Flash and 1K SRAM
GENERAL DESCRIPTION
CS8969 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 30usec
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.
CS8969 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.
