This item is subject to a minimum order quantity (MOQ), and the price per device will be lower for higher quantities. The prices for some representative quantities are shown below. If you want to order a different quantity, enter it below and add it to your cart to see the total cost (you can always delete items from your cart later).
PACKAGING. Please note that you will not necessarily receive your goods in standard packaging, even if you have ordered a quantity equal to, or more than a standard tube quantity. We may break down standard tube lengths into smaller lengths for more efficient shipment.
Devices in surface-mounted packages may be sensitive to absorbed moisture. Such devices supplied in smaller quantities without the manufacturers original moisture-controlled bulk packaging, should be 'baked out' according to the manufacturers recommendations before being subjected to reflow soldering processes. Such devices can however generally be manually soldered without special precautions.

The P87LPC764 is a 20-pin single-chip microcontroller designed for low pin count applications demanding high-integration, low cost solutions over a wide range of performance requirements. A member of the Philips low pin count family, the P87LPC764 offers programmable oscillator configurations for high and low speed crystals or RC operation, wide operating voltage range, programmable port output configurations, selectable Schmitt trigger inputs, LED drive outputs, and a built-in watchdog timer. The P87LPC764 is based on an accelerated 80C51 processor architecture that executes instructions at twice the rate of standard 80C51 devices.
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.
-4.5 V to 5.5 V for P87LPC764HDH.
-2.7 V to 6.0 V operating range for digital functions.
-4 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 P87LPC764 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 uA.
-20-pin DIP, SO, and TSSOP packages.
