Product details
Overview
NCF2960MHN/T0B04CJ from NXP Semiconductors is a single-chip remote keyless entry (RKE) and transponder combo IC integrating a 16-bit RISC microcontroller, on-chip UHF transmitter (315/434/868/915 MHz), HT3/AES-128 calculation unit, 16 KB user EROM, and 2 KB ultra-low-power EEPROM. It enables Combo-Key systems combining vehicle immobilization and RKE in a 4 × 4 mm HVQFN24 package.
For engineers reviewing the NCF2960MHN/T0B04CJ datasheet, NCF2960MHN/T0B04CJ pinout, NCF2960MHN/T0B04CJ application, or NCF2960MHN/T0B04CJ equivalent, key selection considerations include UHF band support, transponder protocol compatibility (HT3/HT-AES/HT-Pro2), battery voltage range (2.1–3.6 V), fractional-N PLL for crystal tolerance compensation, and wettable-flank HVQFN24 packaging for optical solder inspection.
Technical Context
The NCF2960MHN/T0B04CJ implements NXP's third-generation Micro RISC Kernel (MRK III), executing instructions in one machine cycle with Harvard architecture. Its on-chip UHF transmitter uses a 27.6 MHz crystal and supports frequency hopping across 315/434/868/915 MHz bands via fractional-N PLL calibration.
Transponder emulation operates independently of the battery using LF field power, while the RKE function runs from a single lithium cell. Security computation is handled by a hardwired calculation unit supporting 96-bit HT3 and 128-bit AES, with optional software-based algorithm execution in EROM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar remote keyless entry and transponder combo applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCF29A1MHN/T0B04CJ | Same pinout and core architecture; adds integrated 125 kHz LF transmitter for bidirectional communication | Supports advanced PKES (Passive Keyless Entry & Start); requires additional LF antenna and matching | Select when vehicle architecture mandates LF wake-up or encrypted bidirectional handshake |

FAQ
What transponder protocols does the NCF2960MHN/T0B04CJ natively support?
The NCF2960MHN/T0B04CJ natively supports HT3 (96-bit), HT-AES (128-bit), and HT-Pro2 transponder protocols through its hardwired calculation unit. These protocols are fully compatible with NXP's legacy transponder families and enable seamless integration into existing vehicle immobilizer systems without firmware modification. The NCF2960MHN/T0B04CJ also allows custom transponder logic via its ROM library and EROM application space.
Does the NCF2960MHN/T0B04CJ require an external crystal, and what tolerance is acceptable?
Yes, the NCF2960MHN/T0B04CJ requires an external 27.6 MHz fundamental-mode crystal. Its integrated fractional-N PLL compensates for initial crystal tolerances up to ±20 ppm, eliminating the need for tight-tolerance (e.g., ±10 ppm) crystals. This tolerance allowance simplifies component sourcing and reduces bill-of-materials cost while maintaining compliant UHF output accuracy across 315/434/868/915 MHz bands.
How does the NCF2960MHN/T0B04CJ manage power during battery depletion?
The NCF2960MHN/T0B04CJ separates power domains: the UHF RKE function operates from the 2.1–3.6 V lithium cell, while the LF transponder circuitry draws energy directly from the 125 kHz reader field. This ensures immobilizer authentication remains fully functional even with a fully depleted battery. The NCF2960MHN/T0B04CJ also features ultra-low-power sleep modes (<1 μA) and EEPROM retention without backup power.
Can the NCF2960MHN/T0B04CJ drive LEDs directly without external components?
Yes, the NCF2960MHN/T0B04CJ includes dedicated I/O pins with integrated current sources (up to 20 mA) that support direct LED driving without external resistors or transistors. This feature simplifies key fob UI design and reduces component count. Each LED driver pin is individually configurable for on/off, blink, or PWM intensity control via register settings in the NCF2960MHN/T0B04CJ's MCU subsystem.
Is the NCF2960MHN/T0B04CJ qualified for automotive use, and what package features aid manufacturability?
The NCF2960MHN/T0B04CJ is designed to meet automotive reliability requirements and is commonly deployed in AEC-Q200-compliant key fob modules. Its HVQFN24 package features wettable flanks, enabling optical solder-joint inspection (AOI) on production lines without X-ray equipment. This improves yield control and reduces test cost in high-volume automotive manufacturing environments.
