com SC9351 AUDIO SYSTEM CONTROL MCU DESCRIPTION SC9351 is an 8051-based MCU with built-in 64KByte FLASH, 8KByte 2 RAM and abundant on-chip periphery modules including I C, 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.
2 * One I C interface LQFP-64-10x10-0.
5 APPLICATIONS * Desktop audio, car audio * Various operating modes with low power dissipation ORDERING INFORMATION Part No.
