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
Features
„ Tri-band, 27 MHz, 40 MHz and 49 MHz
single-chip radio
„ World-wide unlicensed RF band
„ Reliable, bi-directional data link
„ GFSK modulation
„ 64 kbps max data rate
„ Robust Interference Avoidance
„ Viterbi decoder
„ High tolerant frequency compensation
„ 8051 micro-controller
„ JTAG interface
„ 4-kByte SRAM
„ Mouse and keyboard applications
integrated in 16-kByte ROM
„ 18 programmable GPIO’s
„ Internal regulators & DC/DC converter
„ I2C, UART & SPI Serial Interfaces
„ 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.
