GENERAL DESCRIPTION
CS8953 is a general purpose microcontroller with
extensive peripherals that are suitable for wide range
of application. The CPU is based on an enhanced 1-
Cycle 8051 core that is equivalent to 10 times faster
than a conventional 12-Cycle 8051. Total on-chip
SRAM is 1KB for data storage. There is total 32KB
of embedded flash memory that can be used as
program memory and portion of this can be used as
data flash. The 8051 core has built-in T0/T1/T2
timers and a 16-bit watchdog timer. Embedded in the
CPU core are also two full-duplex UART ports, one
I
2
C master controller, and up to 28 GPIO, and up to 8
external interrupts.
Flexibility in clock includes an on-chip precision
oscillator that have +/-2% accuracy or ultra low power
real time clock, and regular crystal oscillator.
Unused clock sources can be disabled or used as
GPIO pins for best system optimization. The clock
selections are also combined with flexible power
management schemes, including PMM, IDLE, STOP
modes to balance CPU speed and power
consumption. The CPU also includes access
protection for critical registers that improves the
overall reliable system operations.
Other on-chip peripherals include one slave I
2
C
controller, a Programmable Counter Array (PCA) with
6 channels of Capture/Compare/PWM modules.
There is a high performance Analog to Digital
Converter with 3.5usec conversion time. The ADC
can be configured in various modes to meet wide
range of applications.
CS8953 also provides a flexible means of flash
programming that supports ISP and IAP. The
protections of loss of Flash contents are implemented
in hardware. There is also access restriction on
critical registers and low supply voltage detection that
allow CS8953 reliable operations under harsh
environment. The code security is extremely secure
based on sophisticated writer command and ISP
command.
Intended application fields of CS8953 include
Automobile AV system, Home Appliance, and other
embedded applications.
