TMS320F2812ZAYAR

Digital Signal Processor Dsp Overview

The TMS320F2812ZAYAR is a 32-bit digital signal processor from the TMS320C28x family, operating at a maximum frequency of 150 MHz. It features a high-performance static CMOS architecture with a 1.8-V core and 3.3-V I/O. The device integrates 128K × 16 Flash memory, 18K × 16 Single-Access RAM (SARAM), and a 4K × 16 Boot ROM. Key peripherals include two Event Managers for motor control, a 12-bit ADC with 16 channels, enhanced CAN, SPI, SCI, and McBSP interfaces. It supports an external memory interface via a 179-ball MicroStar BGA package.

Digital Signal Processor Dsp Feature Summary

• 150-MHz C28x CPU with Harvard bus architecture and up to 12.5 MSPS 12-bit ADC
• 128K × 16 on-chip Flash with code security module and 18K × 16 SARAM
• External Memory Interface (XINTF) supporting over 1M × 16 total memory expansion
• Motor control peripherals including EVA/EVB event managers and eCAN communication

Digital Signal Processor Dsp Applications

• Advanced Driver Assistance Systems (ADAS)
• Electric Vehicle/Hybrid Electric Vehicle (EV/HEV) powertrain
• Industrial motor drives and factory automation
• Grid infrastructure and power delivery systems

Digital Signal Processor Dsp Procurement Notes

Verify the 'ZA' suffix against official Texas Instruments documentation to confirm specific temperature range or automotive qualification status, as standard datasheets list GHH, ZHH, PGF, and PBK packages. Ensure the component matches the 179-ball MicroStar BGA form factor required for the external memory interface functionality.

Digital Signal Processor Dsp Selection Notes

Select this model when external memory expansion is required, distinguishing it from the F2810 and F2811 which lack the XINTF peripheral. Confirm that the 179-ball BGA package fits the PCB layout constraints and that the 3.3-V I/O levels are compatible with the target system's voltage domains.

Digital Signal Processor Dsp Part Context

The TMS320F2812 belongs to the TMS320C28x DSP generation, designed for demanding real-time control applications. It serves as a bridge between standard microcontrollers and higher-performance floating-point devices, offering fixed-point processing with extensive peripheral integration for industrial and automotive control loops.

Digital Signal Processor Dsp Replacement Considerations

The TMS320F2812-Q1 is the automotive-qualified variant of this device. For pin-compatible upgrades within the same package, consider the TMS320F2811 if external memory is not needed. Higher-performance replacements in the Delfino series include the TMS320F2833x.
