8-bit MCUs have 12-bit A/D, 8-bit D/A, op amp

Featuring a 12-bit A/D converter and dual 16-bit PWMs with 64 MHz operation, the PIC16F(LF)1782/83/84/86 or 87 8-bit microcontroller offers a tiny 28-Lead UQFN 4 x 4 x 0.5 mm package. It has up to 8 Kbytes of flash, 256 bytes of EEPROM, and 1 Kbyte of SRAM. The IC takes just 125 µA typ and 550 µA max at 4 MHz with a 1.8 V supply over the -40°- to 85°C temperature range. The LF versions have sleep currents of just 50 nA typ.

The chip also has an 8-bit D/A converter, a 32 MHz oscillator, three comparators with 50 ns response time, two operational amplifiers, and a fixed voltage reference. It is available in a number of different 28- and 40-pin packages and has EUSART, I2C and SPI interface peripherals. (From $1.18 ea/10,000 — available now.)
