The 256 KB of Flash (organized as 128K x 16) and 34K x 16 of RAM support moderate firmware footprints with room for data buffers. The 88 general-purpose I/O pins give enough flexibility to interface with multiple encoders, solenoids, and display modules without external GPIO expanders. ## Package and thermal management for the 176-HLQFP Without proper stitching, junction temperature can exceed the 125°C maximum under sustained 150 MHz operation in a 105°C ambient. The core supply range is 1.805 V to 1.995 V, so a dedicated 1.8 V or 1.9 V rail is needed — not a shared 3.3 V bus. The I/O bank runs from the same supply, so decoupling should follow the layout guidelines in the datasheet for the exposed-pad QFP.","metaTitle":"TMS320F28234PTPQ C2000 Delfino MCU, 150MHz, AEC-Q100","metaDescription":"Texas Instruments TMS320F28234PTPQ C2000 C28x Delfino 32-bit MCU, 150MHz core, 256KB Flash, 34K x 16 RAM, 88 I/O, -40 to 125°C, AEC-Q100.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"150MHz","Series":"Automotive, AEC-Q100, C2000™ C28x Delfino™","Package":"Tray","RAM Size":"34K x 16","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I²C, McBSP, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"88","Core Processor":"C28x","Package / Case":"176-LQFP Exposed Pad","Product Status":"Active","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"TMS320","Program Memory Size":"256KB (128K x 16)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"176-HLQFP (24x24)","Voltage - Supply (Vcc/Vdd)":"1.805V ~ 1.995V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$38.4100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/29c96fcaaaeb3680d82216c5bdeb6125.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TMS320F28234PTPQ/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to TMS320F28234PTPQ?","answer":"The TMS320F28235PTPQ is a higher-density sibling with more Flash and RAM, but pin-compatible across the same 176-HLQFP package.
