Freescale Semiconductor's new S12ZVC MagniVT mixed-signal microcontroller. The S12ZVC 16-bit MCU is based on a 32MHz S12Z core with 192 KB of flash memory, 12 KB of RAM, 2 KB of EPROM, integrated CAN physical layer, 12-bit analog-to-digital converter (ADC), 8-bit DAC, and more. S12ZVC supports many automotive and industrial communication protocols, including SENT, MSCAN and LIN.
The highly integrated mixed-signal microcontroller includes a 12V regulator, analog peripherals, and automotive / industrial serial protocols on a single chip. S12ZVC is based on a high-performance 16-bit kernel, which includes a 32-bit ALU and a 24-bit address space. The integrated CAN physical layer has high EMI immunity and 8 kV ESD resistance, providing reliable operation in harsh environments. 16-channel 12-bit ADC and a single 8-bit 5 V digital-to-analog converter (DAC) provide analog signal capture and generation. Four pins support 25 mA sink current and one pin supports 20 mA source current to drive high current loads. S12ZVC can operate at high ambient temperatures up to 150 ° C, making it an ideal solution for space-constrained and high-temperature applications.
S12ZVC supports many automotive and industrial communication interfaces. The powerful SAE J2716 SENT (unilateral nibble transmission) serial data protocol is used to communicate with sensors in harsh environments. The MSCAN serial interface is based on the CAN 2.0B protocol and uses an advanced buffer arrangement system that enables predictable real-time behavior, making the protocol suitable for automotive, industrial, and general embedded applications. Two SCI interfaces support the LIN serial protocol.
The company said that target applications include automotive applications, CAN-based sensors, HVAC controllers, lighting control and industrial systems.
