P89LPC932A1

General description

The P89LPC932A1 is a single-chip microcontroller, available in low cost packages, based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system-level functions have been incorporated into the P89LPC932A1 in order to reduce component count, board space, and system cost.

Features

Principal features

• 8 kB byte-erasable flash code memory organized into 1 kB sectors and 64-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage.
• 256-byte RAM data memory, 512-byte auxiliary on-chip RAM.
• 512-byte customer data EEPROM on chip allows serialization of devices, storage of set-up parameters, etc.
• Two analog comparators with selectable inputs and reference source.
• Two 16-bit counter/timers (each may be configured to toggle a port output upon timer overflow or to become a PWM output) and a 23-bit system timer that can also be used as a RTC.
• Enhanced UART with fractional baud rate generator, break detect, framing error detection, and automatic address detection; 400 kHz byte-wide I²C-bus communication port and SPI communication port.
• CCU provides PWM, input capture, and output compare functions.
• High-accuracy internal RC oscillator option allows operation without external oscillator components. The RC oscillator option is selectable and fine tunable.
• 2.4 V to 3.6 V V_DD operating range. I/O pins are 5 V tolerant (may be pulled up or driven to 5.5 V).
• 28-pin TSSOP, PLCC, HVQFN, and DIP packages with 23 I/O pins minimum and up to 26 I/O pins while using on-chip oscillator and reset options.

Additional features

• A high performance 80C51 CPU provides instruction cycle times of 111 ns to 222 ns for all instructions except multiply and divide when executing at 18 MHz. This is six times the performance of the standard 80C51 running at the same clock frequency. A lower clock frequency for the same performance results in power savings and reduced EMI.
• In-Circuit Programming (ICP) allows simple production coding with commercial EPROM programmers. Flash security bits prevent reading of sensitive application programs.
• Serial flash In-System Programming (ISP) allows coding while the device is mounted in the end application.
• In-Application Programming (IAP) of the flash code memory. This allows changing the code in a running application.
• Watchdog timer with separate on-chip oscillator, requiring no external components. The watchdog prescaler is selectable from eight values.
• Low voltage reset (brownout detect) allows a graceful system shutdown when power fails. May optionally be configured as an interrupt.
• Idle and two different power-down reduced power modes. Improved wake-up from Power-down mode (a LOW interrupt input starts execution). Typical power-down current is 1 uA (total power-down with voltage comparators disabled).
• Active-LOW reset. On-chip power-on reset allows operation without external reset components. A reset counter and reset glitch suppression circuitry prevent spurious and incomplete resets. A software reset function is also available.
• Configurable on-chip oscillator with frequency range options selected by user programmed flash configuration bits. Oscillator options support frequencies from 20 kHz to the maximum operating frequency of 18 MHz.
• Oscillator fail detect. The watchdog timer has a separate fully on-chip oscillator allowing it to perform an oscillator fail detect function.
• Programmable port output configuration options: quasi-bidirectional, open drain, push-pull, input-only.
• Port 'input pattern match' detect. Port 0 may generate an interrupt when the value of the pins match or do not match a programmable pattern.
• LED drive capability (20 mA) on all port pins. A maximum limit is specified for the entire chip.
• Controlled slew rate port outputs to reduce EMI. Outputs have approximately 10 ns minimum ramp times.
• Only power and ground connections are required to operate the P89LPC932A1 when internal reset option is selected.
• Four interrupt priority levels.
• Eight keypad interrupt inputs, plus two additional external interrupt inputs.
• Schmitt trigger port inputs.
• Second data pointer.
• Emulation support.

Comparison to the P89LPC932

The P89LPC932A1 includes several improvements compared to the P89LPC932. Please see P89LPC932A1 User manual for additional detailed information.

• Byte-erasability has been added to the user code memory space.
• All of the errata described in the P89LPC932 Errata sheet have been fixed.
• Serial ICP has been added.
• The RCCLK bit has been added to the TRIM register allowing the RCCLK to be selected as the CPU clock (CCLK) regardless of the settings in UCFG1, allowing the internal RC oscillator to be selected as the CPU clock without the need to reset the device.
• Enhancements added to the ISP/IAP code to improve code safety and increase ISP/IAP functionality. This may require slight changes to original P89LPC932 code using IAP function calls. Some ISP/IAP settings are different than the original P89LPC932. Tools designed to support the P89LPC932A1 should be used to program this device, such as Flash Magic version 1.98, or later.
