General Description
RM9000 module is a multiprotocol 2.4 GHz wireless microcontroller (MCU) supporting Bluetooth
®
5.2 Low Energy,
IEEE 802.15.4, IPv6-enabled smart objects (6LoWPAN), proprietary systems, including the TI 15.4-Stack
(2.4 GHz), and concurrent multiprotocol through a Dynamic Multiprotocol Manager (DMM) driver. The device is
optimized for low-power wireless communication and advanced sensing in building security systems, HVAC,
medical, portable electronics, home theater & entertainment, and connected peripherals markets. The highlighted
features of this module include:
• Wide flexibility of protocol stack support.
• Enable long-range and low-power applications using integrated +5 dBm high-power amplifier with best-in-
class transmit current consumption at 85 mA.
• Coin-cell operation at +5 dBm with transmit current consumption of 22 mA.
• Longer battery life wireless applications with low standby current of 0.94 µA with full RAM retention.
• Industrial temperature ready with lowest standby current of 5 µA at 85°C.
• Advanced sensing with a programmable, autonomous ultra-low power Sensor Controller CPU with fast wake-
up capability. As an example, the sensor controller is capable of 1-Hz ADC sampling at 1 µA system current.
• Low SER (Soft Error Rate) FIT (Failure-in-time) for long operation lifetime with no disruption for industrial
markets with always-on SRAM parity against corruption due to potential radiation events.
• Dedicated software-controlled radio controller (Arm
®
Cortex
®
-M0) providing flexible low-power RF transceiver
capability to support multiple physical layers and RF standards.
• Excellent radio sensitivity and robustness (selectivity and blocking) performance for Bluetooth
®
Low Energy
(-105 dBm for 125-kbps LE Coded PHY).
