P89LPC9341

P89LPC9331/9341/9351/9361 8-bit microcontroller with accelerated two-clock 80C51 core, 4 kB/8 kB/16 kB 3 V byte-erasable flash with 8-bit ADCs Rev. 5.1 — 20 August 2012 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...
