Moreover, it incorporates power-saving features such as a programmable watchdog timer, brown-out detection, and a power-on reset circuit, ensuring minimal power consumption. Featuring 23 general-purpose I/O pins, 6 interrupt sources, and 4 8-bit timers/counters, it offers flexibility and precise timing control. Encased in a 28-pin DIP package, the P87LPC762BD is suitable for a wide array of embedded applications that demand low power consumption, high performance, and versatile communication options
Key Features
- An accelerated 80C51 CPU provides instruction cycle times of 300–600ns for all instructions except multiply and divide when executing at 20 MHz. Execution at up to 20 MHz when VDD = 4.5 V to 6.0 V, 10 MHz when VDD = 2.7 V to 6.0 V.
- 2.7 V to 6.0 V operating range for digital functions.
- 2 kbytes EPROM code memory.
- 128 byte RAM data memory.
- 32-byte customer code EPROM allows serialization of devices, storage of setup parameters, etc.
- Two 16-bit counter/timers. Each timer may be configured to toggle a port output upon timer overflow.
- Two analog comparators.
- Full duplex UART.
- I2C communication port.
- Eight keypad interrupt inputs, plus two additional external interrupt inputs.
- Four interrupt priority levels.
- Watchdog timer with separate on-chip oscillator, requiring no external components. The watchdog timeout time is selectable from 8 values.
- Active low reset. On-chip power-on reset allows operation with no external reset components.
- Low voltage reset. One of two preset low voltage levels may be selected to allow a graceful system shutdown when power fails. May optionally be configured as an interrupt.
- Oscillator Fail Detect. The watchdog timer has a separate fully on-chip oscillator, allowing it to perform an oscillator fail detect function.
- Configurable on-chip oscillator with frequency range and RC oscillator options (selected by user programmed EPROM bits). The RC oscillator option allows operation with no external oscillator components.
- Programmable port output configuration options: quasi-bidirectional, open drain, push-pull, input-only.
- Selectable Schmitt trigger port inputs.
- LED drive capability (20 mA) on all port pins.
- Controlled slew rate port outputs to reduce EMI. Outputs have approximately 10 ns minimum ramp times.
- 15 I/O pins minimum. Up to 18 I/O pins using on-chip oscillator and reset options.
- Only power and ground connections are required to operate the 87LPC762 when fully on-chip oscillator and reset options are selected.
- Serial EPROM programming allows simple in-circuit production coding. Two EPROM security bits prevent reading of sensitive application programs.
- Idle and Power Down reduced power modes. Improved wakeup from Power Down mode (a low interrupt input starts execution). Typical Power Down current is 1 µA.
- 20-pin DIP, SO, and TSSOP packages.
