S1JA MCUs with 48MHz Arm Cortex M23 for Low Power Industrial IoT  Sensor Applications

 

Renesas Electronics has released a series of new microcontrollers under its synergy series called S1JA MCUs. These are low cost, Ultra-Low Power microcontrollers with 48MHz Arm Cortex M23 core and integrated programmable analog and security functions. They are targeted to be used in cost sensitive and low power Industrial Internet of Things (IIoT) sensor applications such as flow control meters, multisensor systems, headless medical monitors and instrumentation systems, and single-phase electricity meters.

 

S1JA MCUs Key Features:

  • 256 KB Flash Memory
  • 32 KB SRAM memory
  • Operating Voltage: 1.6V to 5.5V
  • 16-bit SAR ADC (17 channel)
  • 24-bit Sigma Delta ADC (8 channel)
  • 12-bit ADC (1 channel)
  • 8-bit DAC (2 channel)
  • 1 High Speed comparator
  • 2 Low-Power Comparators
  • OPAMP (3)

 

Each MCU integrates a sensor-biasing unit that supplies accurate power to the external sensors. The Ultra-low power capability allows the S1JA MCUs to extend battery life for battery-operated portable and battery backup applications. It consumes a mere 500nA to enable 20-year battery-operated applications that spend extended periods in sleep mode. In addition, the S1JA’s integrated AES cryptography accelerator, True Random Number Generator (TRNG) and memory protection units provide the fundamental blocks to develop a secure system that connects to the cloud. The Renesas Synergy Software Package (SSP) supports the S1JA MCUs with HAL drivers, application frameworks and RTOS. The SSP also includes six new modules that simplify interconnecting the configurable internal analog blocks. Embedded system designers can use either of the Renesas Synergy development environments--e² studio or IAR Embedded Workbench®--to build and customize their designs.

The S1JA MCUs are currently available for purchase from all worldwide distributors of Renesas Electronics.
