Embedded: 32-Bit MCU Has 20-Channel ADC

The MB91470 is ideal for applications that require high-performance analog monitoring. This 80-MHz MCU is based on the company's FR60 32-bit RISC microcontroller core with 32-bit multiplication and addition calculator (MAC) support that has a 72-bit accumulator. The chip has 512 kbytes of flash and 32 kbytes of SRAM. The MCU handles a pair of 12-bit analog-to-digital converters (ADCs) and a 10-bit ADC. Any of the 20 input channels can drive these ADCs, which are integrated with the on-chip pulse-width modulation controllers. The chips are available in 144-pin lowprofile quad flat packages (LQFPs). Pricing starts at $15.
