Ultra-Low Power 8-bit MCU in WLCSP32 Package

The STM8L152K8Y6TR 8-bit MCU from STMicroelectronics targets battery-powered applications with a strong space constraint such as sensors, mobile devices, wearables or their accessories. Delivered in a WLCSP32 package, the STM8L152K8Y6TR offers a tiny footprint of 1.9 x 3.3 mm and only consumes 400nA in the lowest power mode and 200µA/MHz in run mode. Its ballout is a perfect match on the first seven rows of balls with ST's previous 28-ball WLCSP version; ensuring easy migration from 16-Kbyte to 64-Kbyte Flash memory devices.

The high-density and medium+ density STM8L15xx6/8 ultra-low-power devices feature an enhanced STM8 CPU core providing increased processing power (up to 16 MIPS at 16 MHz) while maintaining the advantages of a CISC architecture with improved code density, a 24-bit linear addressing space and an optimized architecture for low-power operations. Operating power supply is 1.65- to 3.6-V (without BOR) or 1.8- to 3.6-V (with BOR). These devices are offered with three temperature ranges, -40 to +85, +105 or +125 degrees C.

The family includes an integrated debug module with a hardware interface (SWIM) which allows non-intrusive in-application debugging and ultrafast Flash programming. All high-density and medium+ density STM8L15xx6/8 microcontrollers feature embedded data EEPROM and low-power low-voltage single-supply program Flash memory.

The devices incorporate an extensive range of enhanced I/Os and peripherals, a 12-bit ADC, two DACs, two comparators, a real-time clock, four 16-bit timers, one 8-bit timer, as well as standard communication interfaces such as two SPIs, an I2C interface, and three USARTs. A 8x40 or 4x44-segment LCD is available on the STM8L152x8 devices. The modular design of the peripheral set allows the same peripherals to be found in different ST microcontroller families including 32-bit families. This makes any transition to a different family very easy, and simplified even more by the use of a common set of development tools.
