Product details
Overview
TMS320LF2406APZAG4 from Texas Instruments is a 32-bit fixed-point DSP controller optimized for digital motor control, featuring a TMS320C2xx CPU core, 40-MIPS performance at 40 MHz, 32K words of on-chip Flash memory, dual Event Manager modules (EVA/EVB), and integrated 10-bit ADC with 16-channel input and 500-ns minimum conversion time - deployed in industrial AC induction and BLDC motor drives.
For engineers reviewing the TMS320LF2406APZAG4 datasheet, TMS320LF2406APZAG4 pinout, TMS320LF2406APZAG4 application, or TMS320LF2406APZAG4 equivalent, key selection criteria include dual EV module support for multi-axis motion control, CAN 2.0B interface compatibility, 100-pin LQFP (PZ) package footprint, and Flash-based in-circuit programmability with code-security protection.
Technical Context
The TMS320LF2406APZAG4 implements a static CMOS C2xx DSP core with instruction cycle time of 25 ns and full code compatibility with TMS320F240/F241/F243/C242 families. Its dual Event Manager modules provide synchronized PWM generation, quadrature encoder interface, and emergency shutdown via PDPINTA/B pins.
It integrates a twin-autosequencing 10-bit ADC with selectable trigger sources from both EVA and EVB, plus dedicated peripherals including SCI, SPI, CAN 2.0B, PLL clock generator, watchdog timer, and 41 GPIOs - all operating from a single 3.3-V supply with three power-down modes.
Key Specifications

Pinout & Package
Package: 100-pin Low-Profile Quad Flat Package (LQFP), body size 14 mm × 14 mm, 0.5-mm pitch, exposed pad optional - designed for high-density motor control PCB layouts with thermal and EMI considerations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PDPINTA (Pin 6) | Power Drive Protection Interrupt A | Falling-edge-sensitive hardware interrupt that forces EVA PWM outputs into high-impedance state during overcurrent/overvoltage fault - critical for IGBT/MOSFET safety in inverter stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DSP controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320LF2407APGEA | 144-pin LQFP, adds External Memory Interface (192K words), extra GPIOs, and additional ADC channels - no change in core peripherals or instruction set. | Required when system needs external program/data memory expansion beyond on-chip Flash/RAM capacity. | Select TMS320LF2407APGEA only if external memory interface or >41 GPIOs are required; otherwise TMS320LF2406APZAG4 offers identical motor control features in smaller footprint. |
| TMS320LC2406APZA | ROM-based variant (32K × 16-bit mask ROM), same 100-pin PZ package, no boot ROM, no Flash security - identical peripheral set and timing specs. | Suitable for cost-sensitive, high-volume production where firmware is finalized and field updates are unnecessary. | Choose TMS320LC2406APZA for fixed-function drives with no firmware update requirement; TMS320LF2406APZAG4 preferred for development, prototyping, or field-upgradable systems. |
Compared with TMS320LF2407APGEA, the TMS320LF2406APZAG4 saves board space and cost while retaining full dual-EV, CAN, and ADC functionality; versus TMS320LC2406APZA, it provides Flash reprogrammability and code security essential for iterative motor control tuning and IP protection.

FAQ
What is the maximum PWM frequency supported by the TMS320LF2406APZAG4?
The TMS320LF2406APZAG4 supports PWM frequencies up to 20 kHz using its dual Event Manager modules, with programmable timer periods down to 25 ns resolution. Each of the 12 PWM channels can be independently configured for center- or edge-aligned operation, and deadband insertion ensures safe switching in bridge topologies - enabling precise control of IGBTs and MOSFETs in motor inverter stages.
Does the TMS320LF2406APZAG4 support CAN FD or only classical CAN 2.0B?
The TMS320LF2406APZAG4 implements the Controller Area Network (CAN) 2.0B protocol only - it does not support CAN FD. Its CAN module complies fully with ISO 11898-1, supporting bit rates up to 1 Mbps and message objects conforming to extended (29-bit) and standard (11-bit) identifier formats - sufficient for most industrial motor control and automotive EPS applications.
How many ADC channels are accessible on the TMS320LF2406APZAG4, and are they all simultaneously sampled?
The TMS320LF2406APZAG4 provides 16 ADC input channels (ADCIN00–ADCIN15), but sampling is sequential, not simultaneous. Its twin autosequencer architecture allows up to 16 conversions per trigger event with zero CPU overhead - triggered by EVA or EVB events - delivering effective throughput of one 10-bit sample every 500 ns, ideal for synchronized current/voltage acquisition in 3-phase motor control.
What is the purpose of the BOOT_EN/XF pin on the TMS320LF2406APZAG4?
The BOOT_EN/XF pin (Pin 48 in PZ package) serves dual roles: as BOOT_EN, it selects boot mode from internal Flash or external memory during reset; as XF (external flag), it functions as a general-purpose output under software control. On Flash devices like the TMS320LF2406APZAG4, this pin must be pulled high externally to enable boot from on-chip Flash - a critical configuration for reliable startup in motor control applications.
Can the TMS320LF2406APZAG4 operate from a 5-V supply, or is 3.3 V mandatory?
The TMS320LF2406APZAG4 requires a nominal 3.3-V supply for VDD, VDDO, and VCCA - operation at 5 V will damage the device. It includes a dedicated 5-V-tolerant VCCP pin for powering external level shifters or optocouplers, but all core logic, I/O, and analog circuitry are strictly 3.3-V CMOS - necessitating proper voltage regulation and isolation between digital and analog domains per TI's layout guidelines.
