Addressing the increasing complexity of highly integrated body applications, Texas Instruments (TI) (NYSE:TXN) announced the sampling of the TMS470PLFx1 generation of software and pin-to-pin compatible automotive MCUs. These are the first TI MCUs to incorporate a comprehensive set of intelligent peripherals dedicated to body applications and offer a high degree of message handling capabilities.
These integrated communication peripherals such as CAN, LIN protocol handler, and multi-buffered SPI efficiently offload the CPU, reducing the number of CPU-cycles needed for communication tasks by up to 80 percent compared to conventional peripherals. Available for immediate sampling, the ARM7TDMI(R) based TMS470PLFx1 MCUs offer up to 512KB of flash memory, optional EEPROM emulation, up to 32KB RAM, and up to 56MHz of 32-bit performance in a temperature range of up to 125°C.
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(TM) 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 processing from the CPU. The high number of timing channels and analog input channels makes separate multiplexer devices redundant and helps in reducing the number of external components, board space and, in turn, system cost.
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(TM) 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.
48 and 56MHz TMS470PLFx MCUs with up to 512KB of flash memory are available in samples today with volume quantities available mid 2007. Package options range from 100 to 176 pin LQFP. Automotive manufacturers and original equipment manufacturers can obtain pricing, hardware and software tools pricing from their local TI sales office.
