MCU provides high voltage connectivity solutions

25 April 2001 DSP, Micros & Memory

Microchip's PIC16C433 PICmicro microcontroller provides an 18 V/40 mA communication interface and offers a high voltage interface for electrically noisy environments. Designed for low EMI emission, the device is intended for consumer and industrial connectivity applications and is ideal for use in domestic appliances, industrial controls, and security and sensor applications.

The small footprint PIC16C433 includes a four-channel 8 bit A/D converter and an 8 bit realtime clock/counter with an 8 bit programmable prescaler. It offers up to 2 kwords of OTP program memory, 128 bytes of data RAM and provides 35 powerful single-cycle instructions. The device also features built-in local interconnect network (LIN) bus protocol capabilities. The LIN protocol is a cost-effective small form factor solution that improves reliability in distributed embedded solutions. With the MCU and the LIN transceiver functioning within a small 18-pin package, the number of external components required is minimised.

Additional capabilities include Microchip's in-circuit serial programming, power-on reset, power-up timer, oscillator start-up timer, power saving SLEEP mode, selectable oscillator options, a watchdog timer with its own on-chip RC oscillator for reliable operation and transceiver thermal shutdown for device protection.
