8-bit S08MP16 MCU for industrial and automotive motor control apps

The new S08 CPU based S08MP16 MCU chip is an 8-bit microcontroller from Freescale Semiconductor for brushless DC (BLDC) motor control applications from industrial drives to automotive fuel pumps.

The S08MP16 MCU is optimized to address motor segment and also supports other motor types, including AC induction.

Multiple, high-speed analog comparators and a 8-channel FlexTimer pulse width modulation (PWM) module provide protection over-current conditions by enabling fast and accurate motor shutdown. For household appliances that need to comply with IEC60730 safety standards, an independently clocked watchdog/COP and cyclic redundancy check (CRC) engine deliver clock failure protection and memory content validation.

The hardware dead-time insertion capability of the FlexTimer improves system accuracy and reduces central processing unit loading when compared with software implementations.

The other key features of the S08MP16 MCU are,

16 KB flash read/program/erase over full operating voltage and temperature
1 KB RAM
12-bit analog-to-digital converter
8-bit modulo counter
Differential programmable gain amplifier
Two programmable delay blocks
Serial communications interface, serial peripheral interface and inter-integrated circuit
Low-power modes and peripheral clock gating for unused modules
Internal clock source
Industrial version: 25MHz bus speed, 2.7-5.5V, -40°C to +105°C
Automotive version: 20MHz bus speed, 2.7-5.5V, -40°C to +125°C

"Intelligent motor control is key in the effort to reduce global energy consumption, and Freescale has a strong legacy of delivering embedded solutions to address this need," said Aiden Mitchell, director of Freescale's Industrial & Multi-Market Microcontroller business. "The S08MP16 delivers a powerful, yet cost-effective, motor control solution for industrial and automotive applications. And, our complementary analog power products and comprehensive development resources make Freescale a 'one-stop shop' for designers looking to simplify their development cycles."
