IC CHIP power transistor electronic chip
FEATURES
• An accelerated 80C51 CPU provides instruction cycle times of 300–600 ns 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.
• Four-channel multiplexed 8-bit A/D converter. Conversion time of 9.3 µS at fOSC = 20 MHz.
• 2.7 V to 6.0 V operating range for digital functions.
• 4 K bytes 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 87LPC767 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 and SO packages.
