产品概述

The new UC3C series has up to 512KB embedded flash and up to 64KB of embedded SRAM. The devices are designed for 3.0 to 5.5V operation with a true 5V operation, qualified as automotive-grade 1 products supporting a temperature range from -40°C to +125°C. Atmel UC3C automotive-qualified MCUs offer all the necessary features required for even the toughest motor control applications. This includes a fast 4-channel PWM controller with a 20-bit precision, dead-time generation and fault protection, a 16-channel, 12-bit pipelined ADC converter, a 4-channel 12-bit DAC converter, an embedded temperature sensor as well as four analog comparators for EMF sensing. With a dual CAN interface, five LIN2.1-compliant independent USARTs, and five I2C-compatible TWIs, the UC3 family is perfectly equipped to communicate via standard in-car networks. The embedded flash vault code protection - a flash security technology that allows the on-chip flash to be partially programmed and locked - the device offers a secure on-chip storage for secret code and software intellectual property.
