PT153S Brings Local Ethernet Option

Single-source brief: Shiqing says its PT153S is a fully domestically developed USB Gigabit Ethernet chip.

What changed

Shiqing Intelligent Technology recently launched the PT153S in Shanghai, IT Home reported.

IT Home cited Electronic Engineering Journal for the announcement.

The chip is not a robotics product. It may serve as a network interface part in devices that need wired Ethernet.

Shiqing describes the PT153S as fully domestically developed. The supplied evidence does not explain its chipmaking, packaging, or component supply chain.

Claimed specifications

According to Shiqing, PT153S uses an in-house RISC-V processor.

The company says it handles USB protocol work and device setup. It also manages Ethernet links and power modes.

PT153S has a USB 3.2 Gen 1 interface. Shiqing lists a top transfer rate of 5 Gbps.

It supports SuperSpeed, High-Speed, and Full-Speed USB modes.

For networking, Shiqing says it supports 10/100/1000M Ethernet auto-negotiation.

Deployment remains unknown

The evidence does not name customers, production volumes, or deployed products.

It also gives no price, factory, packaging, or supply-partner details.

No independent tests were supplied. The speed, feature, and domestic-development claims remain company statements.
