TMS470PLFx1 Processor for Automotive Body Applications

The ARM7TDMI® based TMS470PLFx1 are the first TI MCUs to incorporate a comprehensive set of intelligent peripherals dedicated to automotive body applications and offer a high degree of message handling capabilities. These chips has integrated communication peripherals such as CAN, LIN protocol handler, and multi-buffered SPI.

TMS470PLFx1 MCUs offer up to 512KB of flash memory, optional EEPROM emulation, up to 32KB RAM

Unique High End Timer Offers Greater System Flexibility
TMS470PLFx1 MCUs includes a unique user programmable 32-channel high-end timer (HET), RISC-based co-processor for greater flexibility and accuracy in timing functions like period and pulse measurements, output compare, and pulse width modulations (PWMs). The HET co-processor runs in parallel and completely independently of the ARM7™ CPU, providing significantly higher system performance. TMS470PLFx1 devices also include a multi-buffered, 32-channel 10-bit analog to digital converter (ADC) with a total sampling and conversion time of 1.55 microseconds that, like the HET, offloads CPU processing. The new devices support multiple low power operating modes with a wake-up time of less than twenty micro-seconds enabling hibernate current consumption as low as 25µA. Integrated voltage regulators on the chip enable 5V single voltage-supply resulting into cost savings on system level by eliminating additional external components.

Silicon and Tools Availability
TMS470PLFx MCUs are supported by the comprehensive Code Composer Studio™ integrated development environment (IDE) which integrates debugger, simulator and code generation. Development boards include a superset emulation device as well as emulation boards. TI supports AUTOSAR compliant peripheral software drivers to address standardization and interchangeability requirements.

TI is committed to the automotive market, providing OEMs and system suppliers with a broad digital and analog portfolio of superior-quality, reliable, innovative and cost-effective solutions. TI products address electronics in the car for systems ranging from_ power train to braking to audio and infotainment.

Allowing OEMs to save time to market and reduce development costs for future body design requirements, the TMS470 platform will expand with up to 1.5MB flash memory and higher performance with pin-to-pin compatible devices based on the ARM Cortex™ M3 cores. This allows OEMs to make design decisions today confident that they can reuse existing IP while tapping into advanced 130nm technology node.
