PAW3702DL-TXNT General Datasheet
3in1 SOC Low Power 2.4GHz Wireless Optical Mouse
4.0 System Description
The PAW3702 chips is the low power and high performance 2.4GHz Low Energy SOC. which is integrated 8051
microprocessor, radio transceiver, memory and optical mouse navigation engine.
4.1 Optical Mouse Navigation Engine
The PAW3702 has an optical mouse navigation engine with high precision surface tracking ability that capable in high-speed
motion detection up to the velocity of 30 inches/sec and acceleration of 10g.It has low power architecture supporting
automatic power management modes, configurable sleep and wake-up time which make it suitable for power-sensitive
wireless mouse application.
4.2 8051 Microprocessor Core
The PAW3702 integrates 8-bit MCU that supports the normal 8051 instruction set. It provides low power consumption and
minimal code of the processor to enable developers in achieving 8-bit performance. With its friendly architecture,
applications can be developed easily and quickly.
4.3 Memory
 Program OTP: 16kB OTP is reserved for programming code.
 Executing RAM: 256B internal RAM and 768B external RAM is reserved for temporal data
 TRX composer RAM: 64B RAM is reserved for transmission data
 Optical Mouse Navigation RAM: 192B for motion data
4.4 Radio Transceiver
The PAW3702 is integrated with high performance 2.4GHz radio transceiver to be wireless chips. With the built-in on-chip
balun, PAW3702 system design does not need external balun circuit thus can has minimize BOM. The integrated high
efficiency PA can transmit up to +4dBm RF power for class 2 operation, while the integrated low-IF receiver can provide
excellent sensitivity up to -91dBm and outstanding interference rejection capability.
