Pericom Introduces Industry's Lowest I/O Voltage and Highest Data Rate Universal Level Shifters (ULS)

MILPITAS, CA -- (Marketwired) -- Jan 19, 2016 -- Pericom Semiconductor Corporation (recently acquired by Diodes Incorporated, (NASDAQ: DIOD)), a leading supplier of serial high-speed switching, connectivity, signal-integrity and timing solutions, today announced - two - I2C /SMbus Universal Level Shifter (ULS) products with lowest 0.6V I/O voltage in the industry and two ULS products with highest data rate (280 Mbps).

Designers are faced with varying interface level requirements owing to different technologies of the system blocks. ULS products are required to translate voltage differential when the signal voltages are different between the external source or interface and the internal SoC.

Pericom PI6ULS5V9617A and PI6ULS5V9627A are 2- and 4-Channel Fast Mode I2C Level Shifters supporting 1 MHz frequency, ultra low 0.6V I/O Voltage, and high ESD (8KV HBM) protection. Both are designed for I2C/SMbus Protocol, bi-directional traffic and automatic detection of traffic direction. The current buffer offers driving capability, which can extend I2C/SMbus length up to 1.5 meters of 28AWG copper cable and connect multiple devices on the bus.

Pericom PI4ULS3V502 and PI4ULS3V504 are 2- and 4-Channel Universal Level Shifters supporting up to 280Mbps data rate, 0.85V I/O Voltage and Push-Pull signals for GPIO and other protocols. These ULS devices have proprietary bi-directional traffic and automatic detection of traffic direction features and support data rates required in high speed applications such as clock signals.

"With the proprietary technologies, Pericom ULS can extend signal length supporting ultra low I/O voltage and high speed signal used by the future generation SoC," said John Bai, product marketing director, Pericom Semiconductor. "Pericom ULS have been widely adopted by tier-1 customers in Server, Storage, Networking and Ultra Mobile segments with volume shipment."

Pricing & Availability
The PI4ULS3V502 and PI4ULS3V504 are sampling now while PI6ULS5V9617A and PI6ULS5V9627A are available in production quantities. Additional information and volume pricing quote is available from Pericom worldwide sales, or by requesting a specific product price quote on
