Texas Instruments TMS320LF2407APGES

Overview

TMS320LF2407APGES from Texas Instruments is a 32-bit fixed-point DSP controller optimized for real-time digital motor control, featuring a 40-MIPS C2xx CPU core, dual event-manager modules (EVA/EVB), 16-channel 10-bit ADC with 500-ns minimum conversion time, 32K words of on-chip Flash memory, and integrated CAN 2.0B, SCI, and SPI interfaces. It operates at 40 MHz with 25-ns instruction cycle time and 3.3-V low-power design.

For engineers reviewing the TMS320LF2407APGES datasheet, TMS320LF2407APGES pinout, TMS320LF2407APGES application, or TMS320LF2407APGES equivalent, this device is selected for embedded motion control systems requiring synchronized PWM generation, quadrature encoder interface, emergency shutdown via PDPINT, and deterministic real-time interrupt response in industrial drives and power converters.

Technical Context

The TMS320LF2407APGES implements a static CMOS-based TMS320C2xx DSP CPU core with full code compatibility to TMS320F240/F243 and instruction-set compatibility with F241/C242. Its dual event managers support independent 16-bit timer pairs, 12 PWM outputs (6 per EV), 6 capture inputs, and position encoder interface logic with input qualifier filtering.

It integrates a twin-autosequencing 10-bit ADC triggered by either EVA or EVB, enabling up to 16 conversions per session without CPU overhead. The PLL-based clock module supports programmable multiplication factors, and the external memory interface provides access to 192K words × 16 bits of addressable space (64K program/64K data/64K I/O).

FAQ

What is the maximum operating frequency and instruction cycle time of the TMS320LF2407APGES?

The TMS320LF2407APGES operates at a maximum CPU clock frequency of 40 MHz, delivering 40 million instructions per second (MIPS) with a 25-ns instruction cycle time. This timing is achieved using the internal PLL to multiply the external crystal or clock input, and it is validated across the full −40°C to 85°C temperature range specified for the 'A' grade device.

Does the TMS320LF2407APGES include on-chip Flash memory, and what security features does it support?

Yes, the TMS320LF2407APGES integrates 32K words × 16 bits of on-chip Flash memory organized in four sectors (4K/12K/12K/4K). It supports a password-based "code-security" feature that prevents unauthorized read-out of Flash contents, protecting proprietary motor control firmware from reverse engineering or duplication.

How many PWM outputs and capture inputs does the TMS320LF2407APGES provide, and how are they distributed?

The TMS320LF2407APGES provides 12 PWM outputs and 6 capture inputs, distributed across two independent event manager modules: EVA supplies 6 PWMs (PWM1–PWM6) and 3 capture inputs (CAP1–CAP3); EVB supplies another 6 PWMs (PWM7–PWM12) and 3 capture inputs (CAP4–CAP6), enabling coordinated multi-axis or multi-inverter control.

What communication interfaces are integrated into the TMS320LF2407APGES, and which are exclusive to this variant?

The TMS320LF2407APGES integrates CAN 2.0B, SCI (asynchronous UART), SPI (16-bit synchronous), and JTAG IEEE 1149.1 emulation. Among the LF240xA family, only the TMS320LF2407APGES and TMS320LF2406APZ include CAN; only the TMS320LF2407APGES supports the full external memory interface (192K words × 16 bits).

What is the role of the PDPINTA and PDPINTB pins on the TMS320LF2407APGES, and how do they affect PWM operation?

PDPINTA and PDPINTB are dedicated falling-edge-sensitive power drive protection interrupt inputs. When asserted, they immediately force all PWM outputs associated with Event Manager A (PDPINTA) or Event Manager B (PDPINTB) into high-impedance (tri-state) mode-preventing shoot-through faults in IGBT/MOSFET bridge circuits during overcurrent, overtemperature, or overvoltage events.
