Product details
Overview
PN7221EV/C100Y from NXP Semiconductors is a high-power NFC controller IC supporting NCI 2.2 interface, EMVCo 3.1 digital/analog compliance, and Enhanced Contactless Polling (ECP) for Apple-authorized implementations. It delivers 2.0 W RF output power, integrates dual polling loops (NFC Forum + EMVCo), and operates in VFBGA64 package for payment terminals requiring robust field generation in noisy environments.
For engineers reviewing the PN7221EV/C100Y datasheet, PN7221EV/C100Y pinout, PN7221EV/C100Y application, or PN7221EV/C100Y equivalent, key selection considerations include ECP authorization status, single-host I2C configuration (firmware v1.00), VFBGA64 mechanical compatibility, and integrated DC-DC support for transmitter supply up to 5.7 V.
Technical Context
The PN7221EV/C100Y implements two independent, hardware-switched RF polling loops - one NFC Forum-compliant (v13), one EMVCo 3.1-compliant - each with dedicated EEPROM-stored RF configuration sets for optimized analog performance. MODE pin toggling triggers full NCI stack reset, RF reset, and buffer clearance to ensure transaction integrity.
It supports ISO/IEC 14443-A/B, FeliCa (212/424 kbit/s), ISO/IEC 15693, MIFARE Classic crypto acceleration, and host card emulation up to 848 kbit/s. The device uses a 27.12 MHz crystal or PLL-configurable external clocks (24/32/48 MHz) and features dynamic power control (DPC 2.0) and adaptive waveshape control (AWC) without host MCU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Output Power | 2.0 W maximum - enables strong field generation in metal-rich or shielded enclosures like POS terminals. |
| NFC Standard Support | ISO/IEC 14443-A/B, FeliCa, ISO/IEC 15693, MIFARE Classic - ensures interoperability with global contactless cards and mobile devices. |
| EMVCo Compliance | Full EMVCo 3.1 digital compliance; analog compliance achievable with antenna/matching tuning - required for certified payment readers. |
| Host Interface | I2C up to 3.4 Mbit/s (single-host mode); no SPI active - matches Android-based host systems with simplified layout. |
| Firmware Version | v1.00 pre-initialized - defines baseline NCI stack behavior, ECP readiness, and polling loop initialization sequence. |

| Supply Voltage Range | VDDPA: 1.5–5.7 V; VBAT: 2.4–5.5 V; VDDIO: 2.4–3.6 V - supports flexible power architecture including DC-DC boost for high-power RF operation. |
Pinout & Package
Package: VFBGA64 - plastic thin fine-pitch ball grid array, 4.5 mm × 4.5 mm × 0.9 mm body, 64-ball layout, MSL Level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E6 SPI CITO / I2C1_SDA | I2C data line (bidirectional) | Single-host mode uses I2C SDA; address configurable as 0x28–0x2B via D5/D6 pins for multi-device bus sharing. |
| E5 SPI SCK / I2C1_SCL | I2C clock input | Drives I2C timing at up to 3.4 Mbit/s; requires external pull-up per I2C spec. |
| D6/D5 SPI NSS / I2C1 Adr Bit 0/1 | I2C address select inputs | Set fixed 7-bit I2C address (0x28–0x2B); no SPI NSS function in single-host configuration. |
| B7 IRQ1 | Interrupt output | Signals host on NCI event completion or error; level-triggered, open-drain, requires pull-up. |
| E7 MODE | Polling loop selector input | High = EMVCo mode; Low = NFC Forum mode; hardware-triggered switch forces full NCI reset and RF reinitialization. |
| H5/H4 RXP/RXN | Differential receiver inputs | Accepts balanced antenna signal; internal termination enables noise-immune reception near displays. |
| H1/H3 TX1/TX2 | Differential transmitter outputs | Drive series-tuned antenna; support 2.0 W output with external matching network and VDDPA ≥ 4.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced Contactless Polling (ECP) | Apple-authorized feature enabled post-formal authorization; not active by default - requires OEM licensing and firmware enablement. |
| Dual Independent RF Configuration Sets | EEPROM-stored parameters allow distinct antenna tuning for NFC Forum vs. EMVCo modes - eliminates runtime reconfiguration delay. |
| Dynamic Power Control 2.0 (DPC) | Real-time RF power adjustment without host CPU load - maintains field strength across battery voltage drop or temperature drift. |
| Integrated DC-DC Boost | Generates up to 5.7 V from lower input rails to maximize transmitter output - enables single 3.3 V system supply while delivering 2.0 W RF. |
| Hardware-Based Polling Loop Switching | MODE pin toggle resets NCI stack, clears buffers, and executes RF reset - guarantees deterministic timing for EMVCo certification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN7221EV/C101Y | Firmware v2.02; supports dual-host (I2C + SPI) configuration; same VFBGA64 package. | Required for PCI-compliant payment subsystems using separate security MCU and application processor. | Select when dual-host isolation and updated NCI stack features (e.g., improved EMVCo latency) are needed. |
| PN7220EV/C100Y | No ECP capability; identical pinout, firmware v1.00, single-host I2C only; fully EMVCo/NFC Forum compliant. | Suitable for cost-sensitive or non-Apple-authorized payment terminals where ECP is unnecessary. | Select when ECP is not required and lowest BOM cost is prioritized - same footprint and layout compatibility. |
Compared with PN7221EV/C100Y, PN7221EV/C101Y adds dual-host flexibility and firmware enhancements but requires hardware redesign for SPI routing; PN7220EV/C100Y removes ECP but retains identical mechanical and electrical integration - ideal for drop-in replacement where Apple authorization is excluded.

FAQ
What is the primary function of the PN7221EV/C100Y in a payment terminal design?
The PN7221EV/C100Y serves as the core NFC controller, executing EMVCo 3.1 and NFC Forum-compliant polling loops, driving high-field antennas up to 2.0 W, and managing secure communication with the host processor via I2C. In PN7221EV/C100Y implementations, it operates exclusively in single-host mode with firmware v1.00 and supports ECP upon formal Apple authorization.
Does the PN7221EV/C100Y support dual-host configurations with separate SPI and I2C interfaces?
No - the PN7221EV/C100Y is factory-configured for single-host I2C operation with firmware v1.00. Dual-host capability (I2C + SPI) is exclusive to PN7221EV/C101Y variants. Attempting SPI use on PN7221EV/C100Y will not activate the interface, as HOST_IF_SEL0 is hardwired low and SPI pins remain inactive.
How does the MODE pin affect operation of the PN7221EV/C100Y?
The MODE pin on PN7221EV/C100Y directly selects the active polling loop: logic high enables EMVCo 3.1 mode, logic low enables NFC Forum mode. Each transition triggers full NCI stack reset, RF reset, and buffer clearance - ensuring strict transaction isolation and meeting EMVCo timing requirements without software intervention.
Is Enhanced Contactless Polling (ECP) enabled by default on the PN7221EV/C100Y?
No - ECP is not enabled by default on PN7221EV/C100Y. It requires formal authorization from Apple and subsequent firmware enablement. The PN7221EV/C100Y ships with firmware v1.00 and supports ECP only after OEM licensing and secure provisioning; unauthorized use is prohibited and nonfunctional.
What package and assembly details apply to the PN7221EV/C100Y?
PN7221EV/C100Y uses the VFBGA64 package: 4.5 mm × 4.5 mm × 0.9 mm body, 64-ball layout, MSL Level 3, delivered on 13″ reel (4000 pcs minimum order). Pin assignments match the PN7220/PN7221 family datasheet, with confirmed I2C-only host interface and MODE-controlled polling mode selection.
Can the PN7221EV/C100Y operate without an external crystal?
Yes - PN7221EV/C100Y supports alternative clock sources via its internal PLL: 24 MHz, 32 MHz, or 48 MHz external clocks can replace the default 27.12 MHz crystal. Clock source selection is configured in EEPROM register CLK_INPUT_FREQ (0012h); crystal pins XTAL1/XTAL2 must be left unconnected when using PLL mode.
