SC9351
AUDIO SYSTEM CONTROL MCU
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
LQFP-64-10x10-0.5
APPLICATIONS
* Desktop audio, car audio
