Product details
Overview
TMS320F28053PNQ from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated CLA accelerator, 12-bit ADC (3.75 MSPS), 14 ePWM channels, and analog front-end including 7 comparators, 4 PGAs, and 3 internal DACs - designed for closed-loop motor control in automotive-grade inverter systems.
For engineers reviewing the TMS320F28053PNQ datasheet, TMS320F28053PNQ pinout, TMS320F28053PNQ application, or TMS320F28053PNQ equivalent, key selection criteria include AEC Q100 qualification (–40°C to 125°C), single 3.3-V supply operation, on-chip VREG, and dual-zone security for flash/SARAM/OTP.
Technical Context
The TMS320F28053PNQ implements a Harvard-architecture C28x CPU with atomic instructions and fast interrupt response, coupled with a standalone 32-bit floating-point CLA for parallel real-time control loop execution. Its analog subsystem integrates dual-sample-and-hold ADC, programmable gain amplifiers (gain ≈ 3/6/11), and comparator-to-PWM routing for hardware-accelerated protection.
Clocking uses two internal zero-pin oscillators or external crystal (X1/X2) with missing-clock detection; power management includes POR/BOR and low-power modes. The device supports IEEE 1149.1 JTAG boundary scan and PIE-integrated peripheral interrupts across 42 GPIOs.
