If 8-bit devices are going away—which I sincerely doubt—Microchip Technology isn't going down without a fight. The company's latest 8-bit announcement adds to a pair of PIC families, the PIC12F182X and the PIC16F19XX. In each case, the parts exhibit very low power and an interesting mix of peripherals.
These new MCUs feature active currents of less than 50 μA/MHz and sleep currents down to 20 nA. The PIC12F182X MCUs extend the company's mid-range 8-bit product line into the 8-pin segment, and include mTouch capacitive touch-sensing, and communications peripherals. The PIC16F19XX MCUs add an LCD driver, as well as multiple communications and PWM peripherals.
Microchip claims that these devices provide up to a 50% increase in performance, and 14 new instructions that result in up to 40% better code execution over previous-generation 8-bit PIC16 MCUs. The PIC16F19XX MCUs provide up to 28 kbytes of flash program memory, while the PIC12F182X offers 14 kbytes.
Designers can use the company's F1 evaluation platform for developing with enhanced 8-bit PIC MCUs. The platform includes a 44-pin development board populated with a PIC16LF1937 MCU and prototyping space. The PICDEM lab development kit can be used with the PIC1XF182X MCUs. The kit comes with a development board containing five popular 8-bit PIC MCUs.
The PIC1XF182X and PIC16F19XX MCUs are available in DFN, PDIP, QFN, SOIC, TQFP, TSSOP, and UQFN packages of varying sizes, from 8- to 64-pins. Prices range from $0.69 to $1.74 each, in 10,000-unit quantities.
