STMicroelectronics’ wireless microcontrollers make Sindcon smart meters more efficient and sustainable

STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, announced today its collaboration with Sindcon (Singapore) IoT Technology Pte Ltd, a smart meter provider based in Singapore. 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,” said Paolo Oteri, APeC (Asia Pacific excluding China) Marketing Director at STMicroelectronics. “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.”

“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,” said Chen Deyu, CEO (Chief Executive Officer) at Sindcon.

The project will be Sindcon’s first deployment in Indonesia using the highly integrated STM32WLE5CC wireless MCU from ST, a Sub-GHz wireless microcontroller featuring an Arm® Cortex®-M4 core operating at 48 MHz. The MCU contains 256 Kbytes of Flash memory, 64 Kbytes of SRAM, LoRa® modulation, and AES 256-bit encryption.

With the STM32WLE5, Sindcon’s retrofitted meters contain an advanced battery management system that can support accurate remote readings for up to 10 years.

The meters are currently being retrofitted and will be fully installed by the end of 2023.”
