TMS320R variants from Texas Instruments
TMS320R Overview
What changes between part numbers, and what to check before you lock the BOM — DSPs (Digital Signal Processors).
TMS320R is a Texas Instruments order-code family — not a single orderable MPN. This page lists 4 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Package: LQFP | Operating Supply Voltage: 1.9V | Max Supply Voltage: 3.47V | Min Supply Voltage: 1.81V | Memory Size: 8KB | Frequency: 150MHz | Max Frequency: 150MHz | Interface: I2C, SPI, UART, USART, SCI Other listed variants describe: Package: LQFP | Operating Supply Voltage: 1.9V | Memory Size: 8KB | Max Frequency: 150MHz | Interface: I2C, SPI, UART, USART, SCI, EBI/EMI | Max Operating Temp: 125°C | Min Operating Temp: -40°C; Package: LFBGA | Operating Supply Voltage: 1.9V | Max Supply Voltage: 3.47V | Min Supply Voltage: 1.81V | Frequency: 150MHz | Max Frequency: 150MHz | Interface: I2C, SPI, UART, USART, SCI, EBI/EMI | Max Operating Temp: 85°C.
Across listed variants, watch these parameters: packages: LQFP, LFBGA.
Suffix examples in this family: 2811PBKQ, 2812PGFQ, 2812ZHHA, 2811PBKA. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Columns that actually vary on this page: Package Type. If two rows match on MPN prefix but differ there, they are not interchangeable for production.
Example MPNs: TMS320R2811PBKQ, TMS320R2812PGFQ, TMS320R2812ZHHA, TMS320R2811PBKA.
Key Features
- Footprint / package: LQFP, LFBGALand pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 4 distinct suffix patternsExamples: 2811PBKQ, 2812PGFQ, 2812ZHHA, 2811PBKA. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- DSPs (Digital Signal Processors) — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

Ordering Code Differences
How suffixes on TMS320R map to package, grade, and reel options.
TMS320R uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: 2811PBKQ, 2812PGFQ, 2812ZHHA, 2811PBKA.
What changes between rows: Package Type. Sort the table by these columns when narrowing from base number to a single MPN.
Full MPN examples: TMS320R2811PBKQ, TMS320R2812PGFQ, TMS320R2812ZHHA, TMS320R2811PBKA.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right TMS320R DSPs (Digital Signal Processors)
Match the footprint first
Packages here: LQFP, LFBGA. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For TMS320R, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "TMS320R" — include the full suffix (e.g. 2811PBKQ, 2812PGFQ, 2812ZHHA). RFQ with reel/tube preference and required date code.
