Description

KAmeleon-STM32L4 - starter kit with STM32L496ZGT6 microcontroller
KAmeleon is a development kit with STM32L496ZGT6 microcontroller (ARM Cortex-M4) which is a complete platform for learning programming. The extensive equipment and library supporting all built-in peripherals enable the use of an efficient ARM microcontroller, easily comparable to Arduino. The set has a built-in programmer / debugger ST-Link with a micro-USB port, micro-USB cable is included, so you just need to attach the kit to the computer and start the programming adventure (if using the motor controller it is recommended to use the 12 V power supply included with DC sockets or terminal). The producer has also prepared sample programs that show how to use all the elements that the board is equipped with. An additional advantage of KAmeleon is the connector designed to connect the Analog Discovery 2 analyzer / oscilloscope, thanks to which you can "view" the microcontroller line states.

ST1S10 DC/DC and ST1S12GR power supplies

The ST1S10 is a high efficiency step-down PWM current mode switching regulator capable of providing up to 3A of output current. The device operates with an input supply range from 2.5V to 18V and provides an adjustable output voltage. It operates either at a 900 kHz fixed frequency or can be synchronized to an external clock (from 400kHz to 1.2MHz). The high switching frequency allows the use of tiny SMD external components, while the integrated synchronous rectifier eliminates the need for a Schottky diode. The ST1S10 provides excellent transient response, and is fully protected against thermal overheating, switching overcurrent and output short-circuit.

The ST1S12 is a step down DC-DC converter optimized for powering low-voltage digital cores in HDD applications and, generally, to replace the high current linear solution when the power dissipation may cause high heating of the application environment. It provides up to 0.7A over an input voltage range of 2.5V to 5.5V. A high switching frequency (1.7MHz) allows the use of tiny surface-mount components.

W25Q80DV QSPI Flash memory

The Winbond W25Q80DV (8M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins and power. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The device operates on a single 2.7V to 3.6V power supply with current consumption as low as 1µA for power-down. All devices are offered in space-saving packages.

The Winbond W25Q80DV array is organized into 4,096 programmable pages of 256-bytes each. Up to 256 bytes can be programmed at a time. Pages can be erased in groups of 16 (4KB sector erase), groups of 128 (32KB block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The Winbond W25Q80DV has 256 erasable sectors and 16 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage.

The Winbond W25Q80DV supports the standard Serial Peripheral Interface (SPI), and a high performance Dual/Quad output as well as Dual/Quad I/O SPI: Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 (/WP), and I/O3 (/HOLD). SPI clock frequencies of up to 104MHz are supported allowing equivalent clock rates of 208MHz (104MHz x 2) for Dual I/O and 416MHz (104MHz x 4) for Quad I/O when using the Fast Read Dual/Quad I/O instructions. These transfer rates can outperform standard Asynchronous 8 and 16-bit Parallel Flash memories. A Hold pin, Write Protect pin and programmable write protection, with top, bottom or complement array control, provide further control flexibility. Additionally, the device supports JEDEC standard manufacturer and device identification with a 64-bit Unique Serial Number.
