JA3515 – Transceiver
Wireless Controller IC
Dec, 2004
Overview
The JA3515 is a low-cost, highly
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;
Features
„ Tri-band, 27 MHz, 40 MHz and 49 MHz
single-chip radio
„ World-wide unlicensed RF bands
„ 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
„ Application integrated in 24-kByte ROM
„ 16 programmable GPIO’s
„ Internal regulators
„ I2C, UART serial Interface
„ USB & PS/2 interface
both USB and PS2 are on-chip. The
protocol stack and application software are
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.
