Product details
Overview
F280034SPZ from Texas Instruments is a C28x-based real-time microcontroller with 120 MHz DSP core, IEEE 754 FPU, CLA accelerator, 128KB flash (ECC-protected), 69KB RAM (ECC-protected), and integrated analog subsystem including three 4-MSPS 12-bit ADCs, 16 ePWM channels (8 with 150-ps resolution), and four CMPSS modules. It targets high-efficiency power electronics control in motor drives, solar inverters, and EV charging systems.
For engineers reviewing the F280034SPZ datasheet, F280034SPZ pinout, F280034SPZ application, or F280034SPZ equivalent, this page delivers verified specifications, package mapping to 100-pin LQFP (PZ), functional safety readiness (ASIL B/SIL 2 certified variants), and precise alternative part comparisons for industrial and automotive power conversion designs.
Technical Context
The F280034SPZ implements a dual-core real-time architecture: the C28x CPU executes deterministic control loops at 120 MHz with FPU, TMU, and VCRC acceleration, while the independent CLA runs floating-point math tasks in parallel-enabling simultaneous current/voltage loop execution and fast fault response. Its analog signal chain tightly couples ADC sampling, ePWM dead-band generation, and CMPSS trip-zone triggering for sub-microsecond closed-loop latency.
System-level features include Live Firmware Update (LFU) with banked flash erase optimization, Host Interface Controller (HIC) for external host memory access, and Configurable Logic Block (CLB) with four tiles supporting custom logic integration-extending peripheral capability without FPGA co-processing. All memory blocks feature ECC protection, and security includes JTAGLOCK, zero-pin boot, and dual-zone DCSM.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280037SPZ | 256KB flash, 4 CLB tiles, same 100-pin PZ package and peripheral set | Supports larger control algorithms and CLB-based position manager solutions | Select when >128KB flash or CLB logic expansion is required without changing PCB layout |

FAQ
What is the maximum operating temperature range for the F280034SPZ?
The F280034SPZ operates across a free-air temperature range of –40°C to 125°C and a junction temperature range of –40°C to 150°C. These ratings are specified for the 100-pin LQFP (PZ) package and align with industrial and extended-temperature requirements. Thermal resistance values for the PZ package are documented in Section 6.7 of the official datasheet to support board-level thermal design validation for the F280034SPZ.
Does the F280034SPZ include hardware cryptographic acceleration?
Yes, the F280034SPZ integrates a dedicated Advanced Encryption Standard (AES) accelerator supporting secure firmware updates and configuration data protection. This hardware block operates independently of the C28x CPU and CLA, enabling efficient encryption/decryption without compromising real-time control performance. The AES engine is fully supported in TI's C2000Ware software suite for the F280034SPZ.
How many ADC channels does the F280034SPZ support in the 100-pin PZ package?
In the 100-pin PZ package, the F280034SPZ supports up to 25 single-ended ADC input channels across its three 12-bit, 4-MSPS ADC modules-including two gpdac outputs. This channel count is confirmed in Table 4-1 of the device comparison document and applies specifically to the F280034 variant in the PZ package configuration.
Is the F280034SPZ pin-compatible with other TMS320F28003x devices in the same package?
Yes, the F280034SPZ shares identical pinout and electrical characteristics with all TMS320F28003x devices offered in the 100-pin LQFP (PZ) package-including F280037SPZ and F280039CSPZ-as confirmed in Section 5.1 of the datasheet. This allows direct substitution within the same package family when flash size or CLB requirements permit, without PCB redesign.
What functional safety certifications apply to the F280034SPZ?
The F280034SPZ itself is not certified; however, the automotive-qualified variant F280034SPZ-Q1 (with Q100 PM package) is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. Documentation supporting systematic and hardware safety analysis is available for system-level integration of the F280034SPZ in safety-critical applications.
