Sercomm Corporation (TWSE: 5388), has launched a high performance, multi-band, dual mode LTE-M/NB-IoT module based on Nordic Semiconductor’s nRF91 Series. The ‘TPM530M’ cellular IoT module also integrates a Nordic power management IC (PMIC) and RF front-end module (FEM), delivering a fully featured solution in a compact 14.55 by 14.51 by 1.85 mm package size. The pre-certified Sercomm module is designed for a wide range of space-constrained cellular IoT applications including smart metering, bike sharing, wearables, smart city, security, asset tracking and environmental monitoring.

The Nordic-powered TPM530M provides developers a powerful 64 MHz Arm^® Cortex^®-M33 processor, 1 MB NVM and 256 KB RAM, GNSS, as well as a comprehensive set of peripherals including multiple SPI, UART, I2C, PWM and ADC interfaces, 32 GPIOs, and an extended operating temperature range of of -40 to max. +85 °C. Nordic’s nRF91 Series supports both PSM and eDRX power saving modes. For both LTE-M and NB-IoT the PSM floor current is as low as 2.7 µA, and with an eDRX interval of 655 s the average current is 6 µA for LTE-M and 9 µA for NB-IoT. This ultra low power consumption ensures Sercomm’s module is suitable for applications that demand extended battery lifetime between recharge or replacement.

“The TPM530M is a feature-rich and cost-competitive cellular IoT module ideal for battery-powered applications,” says Ben Lin, President, Sercomm Corporation. Nordic has a proven track record on ultra-low power consumption solutions, and along with the Arm Cortex-M33 processor and compact size of its nRF91 Series module, it provides Sercomm the best performance and cost solution available. “Combined with Nordic’s nRF Connect SDK—which provides developers with the perfect software tool for developing LTE-M/NB-IoT products—the TPM530M will enable the next generation of advanced cellular IoT solutions.”
