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 becom...
