on Dec 9, 2017Dear STM8 users,
ST has just officialy introduced to the market new low-cost, low-power 8-bit MCU from STM8 family. This device is named STM8L001J3 and its key new features are small pin count (8 pins) and tiny package (SO8N).
After introducing in July first 8-pin STM8 MCU (STM8S001J3), new STM8L001J3 complements portofolio of 8-pin STM8 MCUs.
STM8L001J3 belongs to STM8L Value line of ultra-low-power microcontrollers. It offers the best price-to-performance ratio for cost-sensitive applications. With a similar core performance and peripheral set as the STM8L151/152 line, Value line has been optimized in terms of features and configurations to reach a budget price.
Some of important features of STM8L001J3:
- Core and system
- 2 internal clock sources (HSI 16MHz, LSI 38kHz)
- Suply voltage range: from 1.8V to 3.6V
- 6 I/Os
- Timing peripherals
- 8- and 16-bit general purpose timers
- Auto-wakeup unit
- Watchdog
- Memories
- 8k Flash
- 1.5k RAM
- 2k EEPROM
- Conenctivity and debug
- UART
- SPI
- I2C
- Single Wire Interface Module (SWIM)
- Analog
- 2 comparators
You can start your design based on STM8L001J3 with free of charge development tools: Cosmic compiler, STM8CubeMX, Standard Peripheral Library and STVD IDE.
More information you can find on STM8L001J3 webpage.
Hardware getting started: minimum hardware needed for STM8L001J3 is decoupling circuitry (10uF + 100nF). It needs to be applied between VDD and VSS pins.
That's good news. Judging from the diagram it looks like a new Low-Density device with 50% more RAM.
Question: when will a datasheet be available?
As the first STM8L Low Density device has recently been added to STM8 eForth (STM8L051F3) I'd be really interested in working with this device, too. STM8S001J3 support has already demonstrated that interactive programming in 1-wire UART mode is quite useful (it also solved the "PD1/SWIM lock-out problem).
