CST5165A,CST5165S1
The CST5165A/5165S1 series is a 4-bit microcontroller that can play 4-channel melodies or 4-channel ADPCM with PWM direct drive circuits. The resolution of PWM is 8/10/12 bits. They include a low-cost, high-performance CMOS microprocessor. The clock frequency of this rise is usually 8.192 (±3%) MHz. The chip can operate in a wide voltage range from 2.0V to 5.5V. It contains program ROM (PROM) and data ROM (DROM) internally. The maximum program ROM size is 8K words and the maximum data ROM size is 496K bytes. The maximum working SRAM is (256+2) notch. It provides a total of 16 software-programmable I/O ports.

- User register: 2 x 4 bits
Power off mode wake-up function:
-HALT mode Wake up source: Ports A, B, D, and E/CE can wake up from HALT mode to normal mode and perform wake up subroutine.
-RTC Wake up: The clock source is from the internal LRCOSC, and the time period is 1/16/64/128 ms.
* The RTC wake function only supports CST5165S1.
12 input/output pins: Ports A, B, and D can be defined individually as input or output ports.
4 Input/output ports or 4 input only ports or 4 output only ports "Port CE/E/C", as defined by the options:
- If only input ports are used, port E is defined as input port only.
- If an output-only port is used, port C is defined as an output-only port.
- If input/output port is selected, port CE is defined as the input/output port.
Four reset conditions:
- Low pressure reset. (LVR=2.0V)
- Power reset.
- External reset pin. (Low activity)
- Watchdog timer overflowed.
An internal interrupt source:
-PWM is interrupted.
WDT
- Watchdog timer, an option that can be enabled/disabled.
- The WDT period is 256 x 256 x 16/Fsys. (System clock=8.192MHz WDT period is 0.13 seconds)
Audio output:
- Support PWM or DAC mode options.
