DESCRIPTION

SC9351 is an 8051-based MCU with built-in 64KByte FLASH, 8KByte RAM and abundant on-chip periphery modules including I2C, UART, SPI, ADC and RTC, etc.

FEATURES

* In system programming(ISP)

* 2.7-3.6V supply voltage for chip core, together with internal or external LDO.

* 8051 architecture compatible with MCS51 instructions 2~4 clock cycles for per instruction

Dual data pointer to improve the data processing efficiency

* Built-in 64Kx8 FLASH programmed by on-chip program or programmer for program memory or data memory

* Data memory IDATA : 256Byte(compatible with 8051) + 64Byte(save data when power down)

XDATA: 8Kbyte external data memory, low 4K of which can be program memory for Flash programming

* Integrate RTC providing calendar, clock, auto leap-year adjustment, timing alarm clock and clock adjustment.

Built-in 8-bit timer for max. 256 seconds long time timing.

* Maximum 40 general IO pins

* Four 8-bit timers T0/T1/T2/T3, where T0/T1 is the same as that of 8051; T2 supports PWM function

* Extended interrupt module with four external interrupts

* Two UART interfaces.

* One SPI interface.

* 3-channel 8-bit AD converter.

* One I2C interface

* Various operating modes with low power dissipation

APPLICATIONS

* Desktop audio, car audio
