SC9364
8051 MCU WITH BUILT-IN PLL FOR RADIO AND AUDIO CONTROL SYSTEM
DESCRIPTION
SC9364 adopts 8051 structure, integrates 64K*8FLASH, 8K*8RAM,
LDO and RTC modules also provides the function modules of DTS, I2C,
UART, SPI, ADC, LCD, etc. which are applicable in desk-top audio and
car audio control.
FEATURES
* In system programming (ISP)
* 2.7-3.6V power supply, integrate LDO module to power the chip
core; external LDO can also be useful.
* Multi low power dissipation mode
* 8051 structure, compatible with standard MCS_51 instructions.
2~4 clock instruction cycle
Dual data pointer
* Built-in 64Kx8 FLASH can be used as program memory or data
memory; The flash can be programmed by on-chip program or
the programmer.
* Data memory
IDATA: 256Byte (compatible with 8051)+64Byte (store data while
power down, indirect addressing is available)
XDATA: 8Kbyte external data memory, where 4K can be used as
program memory for supporting FLASH programming.
* Integrate RTC module, provide alarm clock and auto switch
function among calendar, clock and leap year, with clock
adjusting function.
* 69 GPIO (SC9364C) in maximum
* Provide 32*4 LCD driver outputs.
* 4 8bit timer: T0/T1/T2/T3. T0/T1 are the same with that of 8051,
T2 supports PWM/CAPTURE function.
* Extended interrupt module, 8-channel external interrupts, 8-
channel internal interrupts.
* 2 UART interfaces.
* 1 SPI interface.
* Integrate 8-channel 8Bits A/D.
* 1 I2C interface.
* Integrate DTS module with internal PLL.
APPLICATIONS
* Desk-top audio, car audio
