Product details
Overview
RF430FRL152HCRGER from Texas Instruments is a 13.56-MHz ISO/IEC 15693-compliant NFC sensor transponder integrating a 16-bit MSP430™ ultra-low-power microcontroller, 2KB FRAM, 4KB SRAM, and a 14-bit sigma-delta ADC. It operates in battery-less (fully passive) or single-cell battery-powered modes and supports resistive temperature sensing via integrated TEMP1/TEMP2 bias pins. Used in contactless industrial and medical wireless sensor nodes.
For engineers reviewing the RF430FRL152HCRGER datasheet, RF430FRL152HCRGER pinout, RF430FRL152HCRGER application, or RF430FRL152HCRGER equivalent, key selection criteria include ISO 15693 RF interface compliance, 1.45–1.65 V supply range, 14 µA standby current (LPM3), FRAM nonvolatility with 10¹⁵ write endurance, and dual-sensor ADC input capability (ADC0/ADC1/ADC2 + TEMP1/TEMP2).
Technical Context
The RF430FRL152HCRGER implements a dual-domain power architecture: RF-AFE-derived VDDH powers analog front-end and voltage doubler (VDD2X), while VDDB supplies digital logic and MCU core. Its ISO/IEC 15693 demodulator and load modulator (RF13M) operate without external components when paired with a 13.56 MHz LC tank (LRES = 2.66 µH, CRES ≈ 52 pF).
On-chip peripherals include Timer_A with three capture/compare registers, eUSCI_B supporting SPI (master/slave) and I²C (up to 400 kHz), CRC16 generator, and LV port logic enabling 0.15 V VOL / (VDDB – 0.15 V) VOH at 400 µA drive strength - critical for low-voltage sensor interfacing.
Key Specifications

FAQ
What communication protocols does the RF430FRL152HCRGER support?
The RF430FRL152HCRGER supports ISO/IEC 15693 and ISO/IEC 18000-3 (Mode 1) RF protocols for contactless NFC reader interaction, plus SPI (master/slave) and I²C (up to 400 kHz) for wired host MCU connectivity. It does not support ISO 14443A/B or NFC Forum LLCP. All protocols are implemented in hardware with no firmware overhead.
Can the RF430FRL152HCRGER operate without a battery?
Yes, the RF430FRL152HCRGER supports fully passive operation using power harvested from the 13.56 MHz RF field via its integrated rectifier (VDDH output). In this mode, it powers the analog front-end, MCU core, and FRAM from VDDH alone - enabling true battery-less sensor tags when used with compatible NFC readers.
What is the purpose of the TEMP1 and TEMP2 pins on the RF430FRL152HCRGER?
The TEMP1 and TEMP2 pins on the RF430FRL152HCRGER serve as programmable current sources for biasing 2-wire resistive temperature sensors (e.g., NTC thermistors). They eliminate the need for external bias resistors or DACs, allowing direct connection of the sensor between TEMP1 and ADC1 or TEMP2 and ADC2 for calibrated temperature measurement.
How much FRAM and SRAM does the RF430FRL152HCRGER include?
The RF430FRL152HCRGER includes 2KB of embedded FRAM for nonvolatile program/data storage and 4KB of SRAM for runtime variables and stack. The FRAM offers 10¹⁵ write endurance and sub-microsecond write times - ideal for frequent sensor logging without wear-out concerns.
What package type and dimensions does the RF430FRL152HCRGER use?
The RF430FRL152HCRGER uses a VQFN-24 (RGE) package measuring 4 mm × 4 mm with 0.5 mm pin pitch and an exposed thermal pad connected to VSS. This compact, lead-free RoHS-compliant package supports automated PCB assembly and thermal dissipation in space-constrained sensor modules.
