STMicroelectronics announces new STM32L4P5 and STM32L4Q5 microcontrollers that bring the performance of the Arm® Cortex®-M4 core to cost-sensitive and power-conscious smart connected devices, including utility meters, industrial and medical sensors, fitness trackers, and smart-home products.
With memory density down to 512KB Flash and 320KB SRAM, ST’s new STM32L4+ MCUs deliver performance with economy. Compact 10mm x 10mm 64-pin and 7mm x 7mm 48-pin package options let designers tackle applications limited by size constraints such as wearable form factors.
Flexibility is assured, with independent power connections for circuitry such as USB and analog peripherals, independent clock domains, and Octal and Quad SPI interfaces for external memory expansion. The new devices also feature a 5Msample/s smart analog-to-digital converter (ADC) that can operate at full speed to minimize acquisition time, or at reduced speed with lower current.
Leveraging ST’s ultra-low-power microcontroller technologies, the new STM32L4+ MCUs feature seven main low-power modes that let designers creatively manage power consumption and wake-up times to minimize energy demand. The devices also support FlexPowerControl, which ensures energy-efficient handling of processing loads, as well as Batch Acquisition Mode for energy-efficient data capture while the CPU is stopped.
Budgetary pricing starts at $3.90 for the STM32L4P5CEU6 with 512KByte Flash in the QFN48 package, for orders of 10,000 pieces per year. Samples are available immediately and full production is ramping up.
