Easy interfacing to faster microcontrollers
Microchip has added two new devices to its PIC16C92X family of 8bit one-time-programmable microcontrollers with integrated liquid-crystal display controller.
The devices also feature a precision internal oscillator that will support full speed (16MIPS) operation from a 3V supply.
In addition, the new family offers full code, pinout and tool compatibility with Microchip's wide portfolio of 8bit microcontrollers.
Key features and enhanced on-chip peripherals available with the PIC18F4XK20/2XK20 family include: 8, 16, 32 and 64Kbyte Flash program memory options; up to 3936byte of RAM; up to 1Kbyte of data EEPROM; a switchable, precision 16MHz internal oscillator with PLL; two-speed oscillator startup; an extended watchdog timer; programmable brown-out reset, with a software-enable option; an enhanced low-power timer; a four-channel, 10bit PWM module with PWM steering; an EUSART with LIN compatibility; a master-mode I2C/SPI module with address masking; a 10bit analogue-to-digital convertor with up to 14 input channels; dual rail-to-rail comparators; and an onboard 1.2V fixed reference.
All eight members of the PIC18F4XK20/2XK20 microcontroller family are supported by Microchip's high-performance development systems, including the free MPLAB integrated development environment (IDE) with Visual Device Initialiser, the MPLAB C18 C compiler, the MPLAB ICD 2 in-circuit debugger, and the low-cost PICkit 2 Debug Express.
The new family is offered in the following package options: 28-pin PDIP, SOIC, SSOP and QFN, 40-pin PDIP, and 44-pin TQFP and QFN.
The 32Kbyte (PIC18F45K20 and PIC18F25K20) and 16Kbyte devices (PIC18F44K20 and PIC18F24K20) are available now for general sampling and volume production is expected in Q4 2007.
The 64Kbyte devices (PIC18F46K20 and PIC18F26K20) are sampling now, and the smaller 8Kbyte devices (PIC18F43K20 and PIC18F23K20) are expected to sample later in the year.
