User manual
ILT254X/ILT254S Bluetooth4.0 LE Module
General Description
The ILT254x module is a cost-effective, low-power,
true system-on-chip (SoC) for Bluetooth low energy
applications. It enables robust BLE master or slave
nodes to be built with very low total bill-of-material
costs. The ILT254x combines an excellent RF
transceiver with an industry-standard enhanced
8051 MCU, in-system programmable flash memory,
8-KB RAM, and many other powerful supporting
features and peripherals. The ILT254x is suitable for
systems where very low power consumption is
required. Very low-power sleep modes are
available. Short transition times between operating
modes further enable low power consumption
