Dec, 2004 JA3515 – Transceiver Wireless Controller IC 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; 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. 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 JA3515 Antenna 27/40/ 49MHz Radio CPU GPIO 24K ROM I2 C 4K RAM I/O UART MODEM USB USB PS/2 PS/2 JA3515 System Diagram 7 mm 7 mm 2004 Jaalaa, Inc.
