The Texas Instruments TMS320F2812PGFA is a high-performance C2000™ 32-bit real-time control microcontroller based on the TMS320C28x CPU architecture, designed for demanding motor-control, digital-power and industrial-control applications.
The CPU operates at up to 150MHz, providing a 6.67ns instruction cycle and up to 150 MIPS processing performance. Its C28x architecture supports high-speed multiply-accumulate operations, fast interrupt processing and efficient execution of control algorithms.
The TMS320F2812 integrates 256KB of on-chip Flash memory and 36KB of single-access RAM, together with boot ROM and OTP memory. The integrated code-security module helps protect Flash, OTP and selected RAM areas from unauthorized access.
A built-in External Memory Interface (EMIF) allows the device to connect to more than 1M × 16 of external memory, with programmable wait states, read/write timing and multiple chip-select signals.
For real-time motor and power control, the device includes two Event Manager modules, EVA and EVB, providing up to 16 PWM channels, capture inputs, quadrature encoder interfaces and general-purpose timers.
The integrated 12-bit ADC provides 16 analog input channels, dual sample-and-hold capability and conversion speeds up to approximately 12.5MSPS, enabling fast current, voltage and sensor measurements in control systems.
Communication peripherals include eCAN, SPI, two SCI/UART interfaces and McBSP, allowing flexible connection to industrial networks, sensors, host processors and peripheral devices.
The MCU also provides up to 56 GPIO pins, three 32-bit CPU timers, watchdog timer, JTAG debugging and low-power IDLE, STANDBY and HALT operating modes.
The specific TMS320F2812PGFA ordering code uses a 176-pin LQFP (PGF) package with external memory interface support and an operating temperature range of -40°C to +85°C.
