STMicroelectronics has announced its collaboration with Sindcon (Singapore) IoT Technology Pte Ltd. The project is adding STM32WLE5 LoRaWAN wireless microcontrollers from ST into Sindcon’s network of more than 50,000 water, gas and energy meters in Jakarta, Indonesia.
“The STM32WLE5 microcontroller (MCU) uses a long-range, low-power wireless radio operating on the LoRaWAN network to enable remote meter reading that addresses Jakarta’s diverse and expansive landscape of urban and forested terrain. As a small system-on-chip (SoC), the STM32 wireless microcontroller also lets customers like Sindcon to pack more features into their smart meters, without increasing the size or form factor of their product.” says Paolo Oteri, APeC (Asia Pacific excluding China) marketing director at STMicroelectronics.
“Sindcon’s smart meters in Jakarta are located inside private apartments, residential areas, industrial water utilities and shopping malls, making meter-reading challenging and expensive. We selected the STM32WLE5 for its high integration benefits to our customers and because it enhances performance, size, security and power consumption,” says Chen Deyu, CEO at Sindcon.
The project will be Sindcon’s initial deployment in Indonesia using high integrated STM32WLE5CC wireless MCU from ST, a Sub-GHz (gigahertz) wireless microcontroller featuring an Arm CortexM4 core operating at 48 MHz (Megahertz). The MCU contains 256 Kbytes of flash memory, 64 Kbytes of SRAM (static random access memory), LoRa (long range) modulation, and AES (advanced encryption standard) 256 bit encryption.
With STM32WLE5, Sindcon’s retrofitted meters contain an advanced battery management system that can support accurate remote readings for up to 10 years.
