Microchip Technology Inc. announced eight new members of its 8bit PIC microcontroller (MCU) family with an integrated LCD module.

According to the company, these additions to the LCD PIC microcontroller family include the world's first 28-pin LCD MCUs for simple, cost-effective display applications requiring embedded control, and the first programmable 80-pin MCUs capable of driving 192 segments for touch screen and segmented LCD displays.

Members of the LCD PIC MCU family features flash program memory, low power consumption and LCD control. Unlike other competing LCD MCUs, Microchip said its flash program memory enables maximum flexibility in code development and field reprogrammability. This family also features nanoWatt Technology, which meets industry low-power design requirements, including the need to drive LCD displays in SLEEP mode. The integrated LCD module is software-configurable, and reduces system components, occupied board space and system costs.

"Microchip's flash LCD MCUs offer the greatest breadth of LCD segment drivers, package sizes and integrated features for embedded control applications," commented Ganesh Moorthy, VP of the Advanced Microcontroller and Memory Division. "These new products, all of which include our industry-leading nanoWatt Technology, offer customers compelling choices that provide solution advantages in their applications."

Main features

The press release stated that the high-pin count PIC18F8490/8390/6490/6390 LCD family members have the performance and features needed for embedded control, and meet the advanced display requirements of the segment and touch screen LCD markets. The integrated LCD driver module is capable of driving 128 to 192 LCD segments in 64- and 80-pin packages, respectively.

Additional features of these devices include 8KB to 16KB of flash program memory options and 768 bytes of SRAM; enhanced LCD module with four multiplex commons and up to 48 segment

drivers; six power-managed modes featuring nanoWatt Technology; a 32kHz to 32MHz internal oscillator; high core performance of up to 10MIPS; 10bit ADC with up to 12 signal channels and 100ksps; two analog comparators, programmable brownout detect and programmable low-voltage detect; MI?C/SPI, EUSART (supports LIN) and AUSART communication protocol support; and four timers and two Capture/Compare/PWM Modules.

Meanwhile, the PIC16F917/916/914/913 MCUs offer 28- and 40/44-pin packaging options for simple, cost-constrained display applications requiring embedded control. Sixty to 96 LCD segments can be driven by the integrated driver. Additional features include 7KB to 14KB of flash program memory options and up to 352 bytes of SRAM and 256 bytes of EEPROM data memory; enhanced LCD module with four multiplex commons and up to 24 segment drivers; an 8MHz internal oscillator; 5MIPS core performance; 10bit ADC with up to 8 signal channels; two analog comparators; SPI, I?C and AUSART communication protocol support; and three timers, two Capture/Compare/PWM Modules and one watchdog timer.

To reduce time-to-market, all eight devices are supported by Microchip's standard, high-performance development systems, including MPLAB Integrated Development Environment (IDE), MPLAB C18 C Compiler, MPLAB ICD 2 In-Circuit Debugger and MPLAB ICE 2000/4000 In-Circuit Emulators.

Target markets for these MCUs include automotive, instrumentation/measurement, appliance, industrial, consumer and communications applications.

The PIC18FXX90 LCD products are available for general sampling and volume production. Samples are already available for the PIC16F916 and PIC16F917 products, with volume production scheduled in December. Samples and volume production for the PIC16F913 and PIC16F914 products are planned for the first calendar quarter of 2005.
