For timing-critical loops — like a 10 kHz control update — the 16 MHz clock provides 1600 instruction cycles per iteration, leaving headroom for interrupt service and housekeeping. ## 1 KB Flash / 128 B RAM — sizing the firmware With 1 KB of Flash and 128 bytes of RAM, this part is sized for a single control task with a few configuration parameters — think a temperature monitor that logs min/max values, a simple timer-based relay controller, or a battery-voltage supervisor. The Flash endurance supports field reprogramming, but the 128 B RAM means no buffering for large data sets; any logging must write directly to Flash or use an external serial EEPROM. ## NRND status — plan the BOM accordingly It remains available for existing production runs and repairs, but TI advises against starting new projects with this order code. For a new design, a current MSP430G2xx or MSP430FRxx variant with larger memory and active status is the safer choice. Sourcing through independent distribution is straightforward — we quote against an RFQ, confirming availability and current pricing at the time of order. ## 16-QFN package — footprint and thermal Housed in a 16-pin QFN with exposed pad (4x4 mm body), the MSP430G2101IRSA16T suits compact two-layer PCBs. Surface-mount reflow follows standard lead-free profiles; MSL rating is typical for this package class.","metaTitle":"MSP430G2101IRSA16T 16-bit MCU, 16 MHz, 1 KB Flash, 16-QFN","metaDescription":"Texas Instruments MSP430G2101IRSA16T 16-bit MCU, 16 MHz core, 1 KB Flash, 128 B RAM, 10 I/O, 1.8V–3.6V, 16-QFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430G2xx","Package":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"128 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"-","Mounting Type":"Surface Mount","Number of I/O":"10","Core Processor":"MSP430 CPU16","Package / Case":"16-VQFN Exposed Pad","Product Status":"Not For New Designs","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2101","Program Memory Size":"1KB (1K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"16-QFN (4x4)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/937fce24b59bfba17c8b94ce6eb9d6e9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2101IRSA16T/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy MSP430G2101IRSA16T and what is the price?","answer":"The MSP430G2101IRSA16T is available to order through independent distribution.
