Ultra-Low-Power and High-Performance Main Controllers (MCUs)

To handle the complex functionalities of smart meters, such as multi-tariff structures, remote communication, and anti-tamper logging, we provide a diverse range of MCU options:

8-Bit Entry-Level Applications: For meters with basic functionality and extreme cost sensitivity, the classic and stable PIC16 series, such as PIC16F720-I/SS and PIC16F720T-I/SS, is the ideal choice.
Enhanced Ultra-Low-Power: For applications requiring battery power (such as gas and water meters), PIC16F721-I/SS, PIC16F721T-I/SS, and the extreme ultra-low-power version PIC16LF721T-I/SS provide exceptional standby power consumption performance.
32-Bit Performance Cores: For advanced meters that need to integrate communication protocol stacks (such as DLMS/COSEM):

ATSAM Series: The ATSAMG55J19B-MU and ATSAMG55J19B-AUT provide superior processing capabilities with the ARM® Cortex®-M4 core.
STM32 Ultra-Low-Power Series: STM32L162RET6TR and STM32L162RET6 (based on Cortex-M3), alongside the more powerful STM32L486RGT6 and STM32L486RGT6TR (based on Cortex-M4), maintain high performance while optimizing battery life.
New Generation Benchmarks: The STM32G0B0RET6 (based on Cortex-M0+) and R9A06G037GNP#AA0 offer an excellent balance of cost-performance and peripheral integration.

High-Reliability Non-Volatile Storage

Smart meters must possess the ability to safely save billing data and event logs during a power outage and must withstand an extremely high number of write cycles:

FRAM (Ferroelectric RAM): For applications requiring instant, unlimited write capability, we recommend our highly integrated solutions:

256Kbit: MB85RS256BPNF-G-JNERE1 and MR45V256AMAZAAT-L.
512Kbit: MB85RS512TPNF-G-JNERE1.

Cost-Effective Solutions: Universal 8-bit controller solutions, such as PIC16F15344-I/SS, often integrate ample high-reliability Flash/EEPROM internally, suitable for data retention in smaller-scale meters.

Efficient Power Management and System Monitoring

Utility equipment demands extreme efficiency and reliability:

High-Efficiency Converters: The MAX17504ATP+T provides compact, low-power DCDC conversion, minimizing internal heat generation in the meter.
Backup Power Management: For scenarios requiring emergency data upload at the moment of power loss, the MAX38888ATD+T backup power manager is critical for data protection.
System Monitoring and Comparison: The MAX9064EUK+T nanopower comparator and NJM45001VP1-TE1 op-amp are used for fine-grained anti-tamper detection and sensor signal conditioning.
