This means the manufacturer no longer produces the device through its standard production lines. ## Core architecture and memory — 384KB Flash, 34KB RAM The MSP430F6458IPZR is built around the 16-bit MSP430 CPUXV2 core clocked at 20MHz. This is the same von-Neumann architecture used across the MSP430F6xx family, with a unified memory map that simplifies code and data access. Program memory is 384KB of on-chip Flash, and the SRAM is 34K x 8 — roughly 34KB. For a metering or HMI application running a real-time operating system, the Flash holds the full firmware image plus a small bootloader partition; the RAM leaves about 8–10KB for the stack and dynamic data after the HAL and driver layer footprint. ## I/O and peripherals — 74 pins, LCD driver, 16-channel ADC With 74 general-purpose I/O lines, this MCU can interface to a keypad matrix, a segment LCD, and several external sensors without needing a port expander. The peripheral set includes a brown-out detect/reset, DMA controller, LCD driver, POR, PWM, and watchdog timer. The LCD driver is a notable inclusion — it drives up to 320 segments directly, which suits utility-meter or thermostat displays. Connectivity covers I²C, IrDA, SCI, SPI, and UART/USART, so the device can talk to serial sensors, wireless modules, or a host processor over a standard bus. ## On-chip data converters — 12-bit ADC and DAC The MSP430F6458IPZR integrates a 16-channel 12-bit successive-approximation ADC and a 2-channel 12-bit DAC. The ADC multiplexes across 16 analog inputs — enough to sample multiple sensor voltages (thermistor, pressure transducer, current shunt) without an external mux. The DAC outputs can generate analog setpoints or bias voltages. For a battery-powered data logger, the ADC's 12-bit resolution gives 4.88 mV per step at a 3.0V reference, which is adequate for 0.5% accuracy on a 1V sensor span. The supply voltage range is 1.8V to 3.6V, which covers two alkaline cells in series (3.0V fresh) or a single Li-ion cell (3.6V full). This means the device is rated for outdoor enclosures, unheated factory floors, or engine-bay-adjacent compartments where ambient temperature stays below 85°C. The 100-LQFP package (14x14mm) is a standard surface-mount footprint with 0.5mm pitch, reflow-compatible with lead-free solder profiles.","metaTitle":"TI MSP430F6458IPZR MCU, 20MHz, 384KB Flash, 100-LQFP","metaDescription":"Texas Instruments MSP430F6458IPZR 16-bit MCU, MSP430 CPUXV2 at 20MHz, 384KB Flash, 34KB RAM, 74 I/O, -40°C to 85°C, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"20MHz","Series":"MSP430F6xx","Package":"Tape & Reel (TR)","RAM Size":"34K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"74","Core Processor":"MSP430 CPUXV2","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F6458","Program Memory Size":"384KB (384K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.0739","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8fbd9c64f52c8ae01790f11db62393ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F6458IPZR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430F6458IPZR in the MSP430F6xx family?","answer":"Within the MSP430F6xx series, devices with the same 100-LQFP package and similar peripheral sets exist, but pin compatibility must be verified against the respective datasheets.
