JA3515 – Transceiver

Wireless Controller IC

Overview

The JA3515 is a low-cost, highly

both USB and PS2 are on-chip. The

protocol stack and application software are

integrated, tri-band, system-on-chip

targeted for wireless keyboard and mouse

applications. The JA3515 can be used as

a complete, high performance PC

transceiver interface for a wireless

keyboard and mouse, using minimum

external components. All necessary

functions, the RF transceiver, baseband,

modem, control logic and I/O interfaces;

integrated in the built-in mask ROM.

The wireless data link runs with very low

latency at data rates up to 64 kbps. The

system incorporates a proprietary media

access control protocol (MAC) that

provides highly reliable wireless data

transfers even in an environment with other

wireless users.
