Product data sheet

1. General description

The P89LPC9331/9341/9351/9361 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 P89LPC9331/9341/9351/9361 in order to

reduce component count, board space, and system cost.

2. Features and benefits

2.1 Principal features

 4 kB/8 kB/16 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. P89LPC9351 and P89LPC9361 also include a 512-byte

auxiliary on-chip RAM.

 512-byte customer data EEPROM on-chip allows serialization of devices, storage of

setup parameters, etc. (P89LPC9351/9361)

 Dual 4-input multiplexed 8-bit ADC/DAC outputs. Two analog comparators with

selectable inputs and reference source.

 Dual Programmable Gain Amplifiers (PGA) with selectable gains of 2x, 4x, 8x, or 16x

can be applied to ADCs and analog comparator inputs. (P89LPC9351/9361)

 On-chip temperature sensor integrated with ADC module.

 Two 16-bit counter/timers (each may be configured to toggle a port output upon timer

overflow or to become a PWM output).

 A 23-bit system timer that can also be used as a real-time clock consisting of a 7-bit

prescaler and a programmable and readable 16-bit timer.

 Enhanced UART with a 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.

 Capture/Compare Unit (CCU) provides PWM, input capture, and output compare

functions. (P89LPC9351/9361)

 2.4 V to 3.6 V VDD operating range. I/O pins are 5 V tolerant (may be pulled up or

driven to 5.5 V).

 Enhanced low voltage (brownout) detect allows a graceful system shutdown when

power fails.

 28-pin TSSOP and PLCC packages with 23 I/O pins minimum and up to 26 I/O pins

while using on-chip oscillator and reset options.
