System Clock (fSYS):

l  Built-in high-frequency 24MHz oscillator (fHRC)

l  As the system clock source, fSYS can be set to 24MHz (3.7-5.5V), 12/6/2MHz (2.4-5.5V) by programmer selection.

l  Frequency Error: Suitable for 4.0V ~ 5.5V and -20 ~ 85 application environment, no more than ±1% of frequency error

Built-in Low-Frequency 128 kHz Oscillator (LRC):

l  Clock source of Base Timer (BTM), which can wake up the SC92F725X from stop mode

l  Clock source of Watch Dog Timer (WDT)

l  Frequency Error:  Suitable for 2.9V ~ 5.5V and -20 ~ 85 application environment, no more than ±4% of frequency error

Low-voltage Reset (LVR):

l  4-level LVR voltage options: 4.3V, 3.7V, 2.9V, 2.3V

l  The default is the Code Option value selected by the user

Flash Programming interface:

l  2-wire JTAG programming  interface

Interruption (INT):

l  9 interrupt sources: Timer0, Timer1, Timer2, INT0, INT2, ADC, PWM, UART and Base Timer.

l  2 external interrupt vectors shared by 6 interrupt ports, all of which can be defined in rising-edge, falling-edge or dual-edge trigger mode.

l  Two-level interrupt priority capability

Digital Peripheral:

l  Up to 14 bidirectional independently controllable I/O interfaces, able to configure pull-high resistor independently

l  P0/P2 ports with 4-level drive capability

l  All I/Os equipped with sink current drive capability (47 mA)

l  11-bit WDT with optional clock division ratio

l  3 standard 80C51 Timer/Counters: Timer0, Timer1 and Timer2

l   Four 8-bit PWM output channels with variable period and individual duty cycle

l   5 I/Os as output of the 1/2-bias LCD COM

l  1 independent communication interface: UART

Analog Peripheral:

l  7-channel 12-bit ±2LSB ADC

n  Built-in 2.4V reference voltage

n  2 options for ADC reference voltage: VDD and internal 2.4V

n  Internal one-channel ADC, where VDD can be measured directly

n  ADC conversion completion interrupt

Power Saving Mode:

l  IDLE Mode: can be woken up by any interrupt.

l  STOP Mode: can be woken up by INT0 , INT2 and Base Timer
