JA3514 –Keyboard & Mouse
Wireless Controller IC / Keyboard / Mouse
Dec, 2004
Overview
The JA3514 is a low-cost, highly
integrated, tri-band system-on-chip
targeted for wireless keyboard and mouse
applications. The JA3514 can be used as
a complete and high performance wireless
mouse, using minimum external
components. JA3514 can be used as a
wireless keyboard together with Keyscan
chip JA3518A. All necessary functions, the
RF transceiver, baseband, modem, control

Mouse interface (Quadrature signals,
SDIO
logic and I/O interfaces are on-chip. The
protocol stack and application software are
stored 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 (MAC) protocol that
provides highly reliable wireless data
transfers even in an environment with
several wireless users.
