MICROCHIP PIC16LC923-04I/L

The PIC16C9XX is a family of low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers with an integrated LCD Driver module, in the PIC16CXXX mid-range family. All PICmicro™ microcontrollers employ an advanced RISC architecture. The PIC16CXXX microcontroller family has enhanced core features, eight-level deep stack, and multiple internal and external interrupt sources. The separate instruction and data buses of the Harvard architecture allow a 14-bit wide instruction word with the separate 8-bit wide data. The two stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches (which require two cycles). A total of 35 instructions (reduced instruction set) are available. Additionally, a large register set gives some of the architectural innovations used to achieve a very high performance. PIC16CXXX microcontrollers typically achieve a 2:1 code compression and a 4:1 speed improvement over other 8-bit microcontrollers in their class. The PIC16C923 devices have 176 bytes of RAM and 25 I/O pins. In addition several peripheral features are available including: three timer/counters, one Capture/Compare/PWM module, one serial port and one LCD module. The Synchronous Serial Port can be configured as either a 3-wire Serial Peripheral Interface (SPI) or the two-wire Inter-Integrated Circuit (I2C) bus. The LCD module features programmable multiplex mode (static, 1/2, 1/3 and 1/4) and drive bias (static and 1/3). It is capable of driving up to 32 segments and up to 4 commons. It can also drive the LCD panel while in SLEEP mode. The PIC16C924 devices have 176 bytes of RAM and 25 I/O pins. In addition several peripheral features are available including: three timer/counters, one Capture/Compare/PWM module, one serial port and one LCD module. The Synchronous Serial Port can be configured as either a 3-wire Serial Peripheral Interface (SPI) or the two-wire Inter-Integrated Circuit (I2C) bus.
