FAQ

What is the maximum operating frequency of the TMS320R2812GHHA CPU core?

The TMS320R2812GHHA features a C28x CPU core with a maximum system clock frequency of 150 MHz (SYSCLKOUT), achieved via its on-chip PLL that multiplies an external 1–30 MHz input clock. This enables instruction cycle times as low as 6.67 ns and supports real-time control loops executing in under 1 µs - critical for high-bandwidth motor and power converter applications. The TMS320R2812GHHA maintains this performance across its full –40°C to 125°C operating temperature range.

Does the TMS320R2812GHHA include on-chip Flash memory, and what is its size and endurance?

Yes, the TMS320R2812GHHA integrates 128 KB of on-chip Flash memory organized as 16-bit words, qualified for ≥10,000 erase/write cycles and data retention exceeding 10 years at 125°C. This Flash is used for program storage and supports in-application programming (IAP) via the boot ROM's Flash API - enabling field firmware updates without external programming hardware. The TMS320R2812GHHA also includes 18 KB of on-chip SARAM for zero-wait-state data and stack operations.

How many analog inputs does the TMS320R2812GHHA ADC support, and what sampling modes are available?

The TMS320R2812GHHA integrates two independent 12-bit ADC modules supporting a total of 16 analog input channels (A0–A15). It supports both sequential sampling (single-channel, up to 12.5 MSps aggregate) and simultaneous sampling (dual-channel, 6.25 MSps per channel) modes. Simultaneous mode ensures <1-ns skew between paired conversions - essential for vector control algorithms requiring phase-aligned voltage and current measurements. The TMS320R2812GHHA ADC uses an internal 3.3-V reference and supports external reference inputs.

What communication interfaces are integrated into the TMS320R2812GHHA?

The TMS320R2812GHHA integrates five serial communication peripherals: one enhanced Controller Area Network (eCAN) module compliant with ISO 11898-1 (CAN 2.0B), one Multichannel Buffered Serial Port (McBSP), one Serial Communications Interface (SCI), one Serial Peripheral Interface (SPI), and a parallel External Interface (XINTF) for external memory expansion. The eCAN module includes 32 message objects and dedicated RAM buffers, while the McBSP supports TI-Audio and I²S protocols. All interfaces are fully register-configurable and share multiplexed GPIO pins.

What package type and ball count does the TMS320R2812GHHA use, and is it RoHS-compliant?

The TMS320R2812GHHA is packaged in a 179-ball MicroStar BGA (ZHH/GHH variant), with a 12 × 12 mm body and 0.8-mm ball pitch. It features an exposed thermal pad on the underside for improved heat dissipation and is RoHS-compliant with lead-free solder finish. This package is documented in TI's SPRS257C datasheet and supports standard BGA reflow profiles. The TMS320R2812GHHA's pinout is distinct from PGF (LQFP) and PBK (LQFP) variants and requires dedicated PCB layout for signal integrity and thermal management.
