Next up is one of our old friends, Infineon, with the model CYPD2103A. This E-Marker chip features a built-in 48MHz Cortex-M0 CPU, 32KB of flash memory, and 4KB of SRAM, supporting repeat programming.
In terms of structure, it integrates timers, counters, oscillators, Type-C baseband physical layer, and UFP (Upstream Facing Port) and EMCA (Electronically Marked Cable Assembly) terminal resistors.
Furthermore, it utilizes Cypress's specialized M0S8 technology and offers three different packaging options to meet various application requirements.
The Injoinic IP2133 supports USB PD3.1 EPR applications, SOP' communication, and EPR mode. Additionally, it integrates hardware-level BMC (Biphase Mark Code) protocol and physical layer protocol.
It also incorporates VCONN diode and Ra resistor, resulting in a simplified BOM and an extremely straightforward application circuit. The built-in memory supports write protection, ensuring data security by preventing unauthorized access or modifications.
The IP2133 is available in two variants: IP2133, which does not support EPR mode, and IP2133_EPR, which does support EPR mode, catering to different usage requirements.
The IP2133H/TH is the flagship E-Marker chip in the IP2133 series and the first product to be certified under the PD3.1 V1.7 standard. It comes in two packaging options:
IP2133H in DFN2 x 2-6L package.
IP2133TH in DFN2 x 2-8L package, featuring additional SCL and SDA pins.
This chip supports USB-C 2.2 standard and PD3.1 specifications, integrating hardware-level BMC protocol and PHY. It also supports commands for obtaining manufacturer information and includes a temperature sensor specifically designed for cables.
IP2133H supports EPR 240W power delivery, SOP' and SOP'' commands, USB4 80G, and is suitable for Thunderbolt 4 and Thunderbolt 3 cables. It allows for four reprogramming cycles and features personalized write protection, providing manufacturers with a comprehensive solution.
Moreover, Injoinic IP2133H offers a WLCSP-6B package to cater to various cable requirements.
