NXP Semiconductors SLN-POS-RDR

Overview

SLN-POS-RDR from NXP Semiconductors is a pre-certified point-of-sale (POS) reader solution integrating PCI PTS 4.1 and EMVCo Level 1/2 contact and contactless payment stacks, Kinetis K81 secure MCU, Cirque SecureSense AFE, PN5180 NFC front-end, and TDA8035 contact card reader - enabling rapid integration of chip-and-PIN, NFC, smart card, and MSR functionality into commercial kiosks, self-checkout terminals, and unattended payment devices.

For engineers reviewing the SLN-POS-RDR datasheet, SLN-POS-RDR pinout, SLN-POS-RDR application, or SLN-POS-RDR equivalent, this solution delivers certified software stacks, hardware reference designs, tamper-resistant MCU architecture, dual-display support (segment LCD and QVGA TFT), and full documentation to accelerate EMV-compliant payment system development without recertification risk.

Technical Context

The SLN-POS-RDR integrates two primary hardware modules: TWR-POS-K81 (featuring K81FN256 MCU with DryICE security engine and Cirque K4 SecureSense AFE) and TWR-POS-PN5180 (housing PN5180 NFC IC and TDA8035 contact reader). It runs NXP's EMV Level 1 contact/contactless stacks and Cardtek's licensed EMV Level 2 stacks, all pre-validated by FIME and UL Transaction Security.

Hardware interfaces include SPI between K81 and PN5180/TDA8035, QuadSPI XIP for encrypted external flash, USB CDC for host communication, and dedicated GPIOs for tamper mesh, buzzer, LEDs, and display control - all aligned with PCI PTS physical security requirements including side-channel resistance and active tamper detection.

FAQ

What certifications does the SLN-POS-RDR hold out of the box?

The SLN-POS-RDR is delivered with full PCI PTS v4.1 certification as a PIN Entry Device (PED) and EMVCo pre-certification for Level 1 and Level 2 contact and contactless stacks - validated by UL Transaction Security and FIME. These certifications apply to the complete reference hardware/software configuration, allowing integrators to leverage the reports during their own product certification process without repeating foundational testing.

Does the SLN-POS-RDR include source code for the EMV Level 2 stack?

No - the EMV Level 2 contact and contactless stacks in the SLN-POS-RDR are provided by Cardtek as licensed binary components. The SLN-POS-RDR package includes Cardtek's EMV L2 HAL (shim layer), demo application, and kernel profiles, but full source code requires a separate licensing agreement directly with Cardtek per their commercial terms.

Can the SLN-POS-RDR support magnetic stripe reading (MSR)?

Yes - the SLN-POS-RDR reference design accommodates magnetic stripe reader (MSR) integration via its expansion interface and firmware framework. While the base kit does not include an MSR module, the hardware layout, signal routing, and software architecture (including POS modules for USB communications and system initialization) are explicitly designed to support third-party MSR add-ons compliant with PCI PTS swipe path requirements.

What display interfaces does the SLN-POS-RDR support?

The SLN-POS-RDR supports two display options: a low-cost two-line character segment LCD and a higher-resolution 3.2" QVGA TFT color display. Both are connected via parallel GPIO and controlled through the integrated eGUI middleware and display driver modules in the KSDK-based firmware - with full initialization, rendering, and touch feedback logic included in the reference software.

Is the Cirque SecureSense AFE included as hardware in the SLN-POS-RDR kit?

Yes - the SLN-POS-RDR includes the Cirque K4 SecureSense analog front-end (AFE) as part of the TWR-POS-K81 board. This AFE enables PIN entry obscuration across the capacitive sensor grid without requiring physical shielding of PCB traces, satisfying PCI PTS requirements for PIN capture security and reducing mechanical design complexity in the final enclosure.
