Descripción general

Description

ST21NFCJDBGWRA7 is a device code for STMicroelectronics’ ST21NFC NFC controller family. The ST21NFC family provides NFC capability to enable contactless communication in cards, tags, readers, and devices such as wearables and mobile devices. Key points:
- NFC/RF: NFC Forum-compliant radio and protocol stack (typical support for common standards such as ISO/IEC 14443 and ISO/IEC 15693; supports card emulation, reader/writer, and peer-to-peer modes as configured).
- Host interface: Usually SPI or I2C to connect to a host microcontroller.
- Security: Often includes cryptographic features for secure transactions, keys, and secure element integration options.
- Package/variant code: The suffix JDBGWRA7 is a manufacturing/lot/revision code, not a feature set, and varies by production lot.
For exact capabilities, performance, interfaces, and pinout of this specific revision, consult STMicroelectronics’ datasheet and product selector for ST21NFCJDBGWRA7.

Package

Wafer-Level Chip-Scale Package (WLCSP).

Pinout

Pin count: 32 pins (32‑pin package).
Function: ST21NFCJDBGWRA7 is an NFC front‑end IC (NFC controller/transceiver) for 13.56 MHz contactless communication, supporting standards such as ISO/IEC 14443 (Type A/B) and ISO/IEC 15693, with an interface to the host MCU.

Manufacturer

- Manufacturer: STMicroelectronics (ST).
- What kind of company: A multinational semiconductor company that designs and manufactures integrated circuits and electronic components (MCUs, sensors, MEMS, NFC/RFID, power management), headquartered in Geneva, Switzerland.

Application

Typical application areas for ST21NFCJDBGWRA7 include:
- Secure contactless payments and wallets
- Transit/ticketing solutions
- Access control badges
- Secure identity (eID, national IDs)
- Loyalty programs and smart posters
- NFC-enabled IoT devices with embedded secure element
- Anti-counterfeiting and brand protection

Equivalent

ST21NFCJDBGWRA7 is an STMicroelectronics NFC secure-element MCU (ST21NFC family). There is no published 1:1 cross-reference for this exact part. Equivalents depend on required features (memory, crypto engine, ISO standards). Potential close alternatives from other vendors include NXP PN66x secure-element families or Infineon SLE78/SLF7xx series with NFC front-ends, but compatibility varies. For a precise match, use ST’s cross-reference tool or contact STSupport with your specs.
