Renesas has announced 32bit microcontrollers for automotive comfort and body use, with 0.35mA consumption at 1MHz.
There are 19 devices in the V850E2/Fx4-L series.
"The MCUs offer peripheral functions for applications such as roof or window lifters; door, seat and light modules; HVAC [heating, ventilation, and air conditioning]; and body control modules," said the firm.
Peripherals including PWM generation, up to two CAN interfaces, and eight DMA (direct memory access) channels.
"Verified Autosar microcontroller abstraction layer software drivers [MCAL] are scheduled to be prepared," said the firm. "Renesas' MCAL software drivers can be obtained as a stand-alone software package or integrated in a complete basic software stack in cooperation with partner companies."
A power saving feature is the 'sequencer' which supports hardware monitoring of digital inputs in deep stop mode without any usage of the CPU or memory.
When it detects activities at the digital inputs, it kicks the core from deep stop mode to run mode.
"A further unique feature is the LIN master controller which supports the automatic LIN frame detection without CPU interactivity," said Renesas.
Maximum clock speeds vary from 48 to 64MHz, with 1.81DMIPS/MHz.
"With the adoption of Autosar and increased system functionality, there is growing demand for larger memory capacity. The MCUs address this demand by providing flash memory from 256kbyte up to 1.5Mbyte in packages with pin counts ranging from 64 to 176," said Renesas.
To comply with the Autosar, system protection functions including a memory protection unit and system register protection have been added.
Samples are available now, with mass production scheduled to begin early 2013.
