Product details
Overview
TMS320R2812ZHHA from Texas Instruments is a 32-bit C28x fixed-point digital signal processor (DSP) optimized for real-time control in motor drives, power converters, and industrial automation. It features 150-MHz CPU clock, 128 KB on-chip Flash memory, 18 KB RAM (including 4 KB boot ROM), dual event managers (EVA/EVB), 16-channel 12-bit ADC with 80-ns conversion time, and integrated eCAN, SCI, SPI, and McBSP peripherals. The device operates at 3.3-V I/O and 1.8-V core supply in industrial temperature range (–40°C to 105°C).
For engineers reviewing the TMS320R2812ZHHA datasheet, TMS320R2812ZHHA pinout, TMS320R2812ZHHA application, or TMS320R2812ZHHA equivalent, this page delivers verified technical context, package-specific pin assignments, functional timing constraints, peripheral integration details, and validated alternative options for real-time embedded control design.
Technical Context
The TMS320R2812ZHHA implements a Harvard architecture with separate program and data buses, enabling simultaneous instruction fetch and operand access. Its C28x CPU supports single-cycle 32×32-bit multiply-accumulate (MAC), 32-bit barrel shift, and IEEE 754-compatible floating-point emulation via library routines.
Real-time control capability is enhanced by two independent Event Manager modules-each with three GP timers, six full-compare PWM outputs, quadrature encoder interface, capture units, and programmable dead-band generation. The on-chip 16-channel 12-bit ADC achieves 80-ns conversion time with simultaneous sampling support across two channels.

FAQ
What is the maximum operating frequency of the TMS320R2812ZHHA CPU?
The TMS320R2812ZHHA CPU operates at a maximum system clock frequency of 150 MHz (SYSCLKOUT), derived from an internal PLL that multiplies the input clock (XCLKIN) by up to 10×. This frequency is sustained across the full industrial temperature range (–40°C to 105°C) under recommended operating conditions specified in SPRS257C Section 6.2.
Does the TMS320R2812ZHHA support external memory expansion?
Yes, the TMS320R2812ZHHA includes a dedicated External Interface (XINTF) module that supports up to 1 MB of external memory across four zones. It provides programmable wait-state control, asynchronous/synchronous read/write timing, and ready-signal handshake-features confirmed in SPRS257C Sections 3.5 and 6.21–6.26.
How many analog input channels does the on-chip ADC support?
The TMS320R2812ZHHA integrates a 12-bit analog-to-digital converter with 16 single-ended analog input channels (ADCINA0–ADCINA15). It supports both sequential and simultaneous sampling modes, with simultaneous dual-channel acquisition enabled via SMODE = 1 configuration per SPRS257C Section 6.29.7.
What communication interfaces are built into the TMS320R2812ZHHA?
The TMS320R2812ZHHA includes eCAN 2.0B, SCI (asynchronous UART), SPI, and McBSP (synchronous serial) interfaces. All are fully integrated with DMA support and share GPIO pins via multiplexing. The eCAN module implements 32 message objects and FIFO-based transmission per SPRS257C Section 4.4.
Is the TMS320R2812ZHHA pin-compatible with other R281x devices?
No-TMS320R2812ZHHA uses the 179-ball ZHH BGA package, while TMS320R2811 uses a 128-pin PBK LQFP and TMS320R2812PGFA uses a 176-pin PGF LQFP. Pinouts differ across packages; the ZHH ball map is unique to this variant and documented in SPRS257C Figure 2−1.
