Helping to stimulate the 8-bit microcontroller market, Microchip Technology Inc. has increased the performance of one-time-programmable (OTP) devices destined for low-cost display applications.
According to Microchip, PIC16C925 and PIC16C926 MCUs with on-board LCD controllers let designers customize displays for certain applications or cost points. With up to 8Kwords of OTP program memory, the chips give low-cost applications richer information display without the use of multiple ROM microcontrollers, the Chandler, Ariz.-based company said.
As the second-largest 8-bit MCU supplier in 2000, behind Motorola, Microchip has continued to innovate in order to slow the market's transition to higher-end parts, according to a report by IC Insights Inc.
By reducing the feature sizes used to make PIC devices, the company has been able to add larger program memory and more peripherals-including analog, application-focused, software-configurable functions-on chip, while keeping prices and operating voltages down, the Scottsdale, Ariz., research firm said.
For high performance in battery-operated systems, Microchip has included five channels of 10-bit analog-to-digital converters on the new devices, as well as clock speeds of 20MHz and 200ns instruction cycles. The devices also feature 176 to 336 bytes of RAM.
The PIC16C92x family has an operating voltage range of 2.5 to 6V and consumes less than 2 milliamps typical in 5.5V operation at a frequency of 4MHz.
Additional features include 60 special-function hardware registers, an eight-level-deep hardware stack, interrupt capability, 52 I/O pins, pulse-width modulation output, a Synchronous Serial Port supporting SPI and I2C buses, and brownout detection circuitry for brownout reset.
In 10,000-piece quantities, the PIC16C925 is priced at $4.33 and the PIC16C926 is $4.70. Samples are available, with volume shipments planned for April 2001.
