STMicroelectronics EVLONEPCC

Overview

EVLONEPCC from STMicroelectronics is a compact USB Type-C® to 6-way female Picoflex IDC flat ribbon cable adapter designed to enable UART communication between ST-ONE/ST-ONEMP evaluation boards and the STEVAL-PCC020V2 interface board. It supports CC1/CC2-based UART mapping, measures 37.1 × 13.4 × 9.6 mm, and requires no external power.

For engineers reviewing the EVLONEPCC datasheet, EVLONEPCC pinout, EVLONEPCC application, or EVLONEPCC equivalent, this adapter enables direct configuration of ST-ONE/ST-ONEMP parameters via PC GUI through a routed UART channel over USB Type-C, with verified mechanical polarity sensitivity and 1.27 mm pitch Picoflex interconnection.

Technical Context

The EVLONEPCC implements a passive signal-routing bridge: USB Type-C plug (J2) connects to the EVLONEx board's USB-C port, while its internal traces route CC1 and CC2 lines-configured as USART TX/RX-to the 6-way Picoflex connector (J1) for connection to STEVAL-PCC020V2. No active ICs or level-shifting circuitry are present.

All signal paths are direct copper traces with discrete 0 Ω (R4), 47 Ω (R11), and 1 kΩ (R13) resistors for termination and pull-up functions per ST reference design DB4830. The adapter relies entirely on host-side UART mapping configuration (APPL_SETUP disabled, USART_enable = CC1/CC2, programming mode enabled) to function.

FAQ

What is the primary function of the EVLONEPCC adapter?

The EVLONEPCC is a passive hardware interface that routes UART signals (TX/RX) from the CC1 and CC2 pins of a USB Type-C port on ST-ONE/ST-ONEMP boards to a 6-way Picoflex connector, enabling direct communication with the STEVAL-PCC020V2 interface board without additional level shifters or protocol translation.

Why does the USB Type-C connection require correct orientation?

Because the EVLONEPCC uses only CC1 and CC2 pins for UART-pins assigned differently on each side of the reversible USB Type-C plug-reversing the plug swaps TX and RX paths. ST documentation explicitly states reversal is required if initial communication fails, confirming strict pin-direction dependency.

Does EVLONEPCC support USB data transfer or power delivery?

No. EVLONEPCC contains no USB transceivers, VBUS switching, or PD controller circuitry. Its sole purpose is CC-line UART signal routing. Only CC1, CC2, GND, and shield connections are implemented; D+/D−, VBUS, and SBU pins remain unconnected per DB4830 schematic.

Can EVLONEPCC be used with evaluation boards other than ST-ONE/ST-ONEMP and STEVAL-PCC020V2?

Only if those boards replicate identical UART-over-CC1/CC2 pin mapping and 1.27 mm pitch 6-way Picoflex pinout. ST's DB4830 confirms compatibility is limited to ST-ONE/EVLONE65W, ST-ONEMP/EVLONEMP, and STEVAL-PCC020V2 - no generic or cross-platform support is specified or validated.
