Low-Power Bluetooth Module Low-Cost Wireless Ble232SA-A St
Bluenrg-2 wireless Module
Description
BLE232SA/UA series module is designed based on ST company's
BlueNRG-2. The BlueNRG-2 is a very low power Bluetooth low energy
(BLE5.0)single-mode system-on-chip compliant with Bluetooth
specification.
The BlueNRG-2 extends the features of the award-winning BlueNRG
network processor, enabling the usage of embedded Cortex M0 for
running user application code.
The BlueNRG-2 includes 256kB of programming Flash memory, 24 kB of
static RAM memory with retention (two 12kB banks) and SPI, UART,
I2C standard communication interface peripherals. It also features
multifunction timers, watchdog, RTC and DMA controller.
An ADC is available for interfacing with analog sensors, and for
reading the measurement of the integrated battery monitor. A
digital filter is available for processing PDM stream.
The BlueNRG-2 offers the same excellent RF performance as the
BlueNRG radio, and the integrated high-efficiency DC/DC converter
keeps the same ultra-low power characteristics, but the BlueNRG-2
improves the BlueNRG sleep mode current consumption allowing a
further increase in the battery lifetime of the applications.
