STMicroelectronics, a global semiconductor leader, announced an extraordinary collaboration with Sindcon (Singapore) IoT Technology Pte Ltd of Singapore – one of the premier smart meter providers based there – aimed at revolutionising smart metering by installing STM32WLE5 LoRaWAN(r) wireless microcontrollers into Sindcon’s extensive network of over 50,000 water, gas and energy meters in Jakarta, Indonesia. This groundbreaking partnership promises to change the face of smart metering forever
This groundbreaking project relies on the STM32WLE5 microcontroller as its heart. Leveraging LoRaWAN network technology, this MCU ensures long-range low power wireless technology for remote meter reading in Jakarta’s varied terrain which includes urban and forested areas alike – while providing seamless retrieval of accurate data across this dynamic landscape.
Paolo Oteri, Asia Pacific Excluding China Marketing Director at STMicroelectronics, stressed the significance of their collaboration. Oteri highlighted how Sindcon was able to add features without increasing size or form factor; something the STM32 wireless microcontroller allows. He further elaborated how this scalability will meet evolving smart meter technology demands.
Sindcon’s smart meters are strategically installed throughout Jakarta, in areas including private apartments, residential areas, industrial water utilities and shopping malls. Their use creates logistical difficulties and expenses associated with reading them all at the same time; hence the selection of STM32WLE5 was motivated by its integration benefits, performance enhancements, compact size, enhanced security features and power efficiency benefits.
Sindcon’s first deployment in Indonesia employing ST’s highly integrated STM32WLE5CC wireless MCU marks their inaugural deployment of their sub-GHz wireless microcontroller with Arm Cortex M4 core running at 48 MHz for data processing power and offers ample 256 Kbytes Flash Memory, 64 Kbytes SRAM Memory and LoRa(r) modulation for efficient communication while boasting AES256 encryption to provide data security.
Sindcon’s retrofitted meters now include advanced battery management systems based around STM32WLE5 modules that offer accurate remote readings for up to an impressive 10 years, guaranteeing long-term sustainability and efficiency.
STMicroelectronics and Sindcon have come together to advance smart metering technology in a significant way. By seamlessly incorporating LoRaWAN wireless microcontrollers into Jakarta’s metering infrastructure, this partnership promises to revolutionize data collection and management in this region. As demand for efficient smart metering solutions continues to increase, this collaboration sets an impressive standard of innovation within this sector.
What Is SRAM
SRAM stands for Static Random-Access Memory and is a volatile semiconductor memory used extensively in computers and electronic devices for rapid data storage and retrieval. SRAM differs from dynamic random-access memory (DRAM), another common form of computer memory, in that its contents do not need to be regularly refreshed to remain effective.
Key Features of SRAM Include:
Volatility: SRAM is a volatile memory type, meaning its data will be lost once power has been switched off. By contrast, non-volatile memories like flash memory will retain their information even after it has been disconnected from power sources.
Speed: SRAM memory offers extremely quick access to stored information, making it ideal for use as cache memory on computers where rapid retrieval of stored information is essential for performance.
Refresh-Free Memory Cells: In contrast with DRAM, SRAM does not need frequent refreshing of its memory cells to retain data. Each cell in SRAM typically consists of a flip-flop circuit which stores information as long as power remains connected.
Higher Power Consumption: SRAM consumes more power than other memory types such as DRAM or NAND flash memory due to its continuous flip-flop circuits’ operation, thus necessitating more electricity to operate them.
SRAM Memory in Caches: SRAM memory is frequently utilized as a cache in computer systems for temporarily storing frequently accessed information. Due to its speed and ability to provide fast data access for processing by CPUs, SRAM makes an ideal candidate for such use.
Lower Capacity: SRAM cells are larger and more complex than those found in DRAM, making production more costly and limiting its capacity. Because of this, SRAM typically serves smaller high-speed memory needs.
