MCU 32-Bit KL04 ARM Cortex M0+ RISC 8KB Flash 1.8V/2.5V/3.3V 32-Pin LQFP T/R, MKL04Z8VLC4R, NXP

Описание

The Kinetis KL0 MCU family is the entry point into the Kinetis L series based on the ARM Cortex -M0+ core. The KL0 ultra-low-power MCUs provide a bridge for 8-bit customers migrating into the Kinetis portfolio and is software and tool compatible with all other Kinetis L series devices.

Ultra-Low-Power

• Next-generation 32-bit ARM Cortex-M0+ core: 2x more CoreMark/mA than the closest 8/16-bit architecture
• Single-cycle fast I/O access port facilitates bit banging and software protocol emulation, keeping an 8-bit look and feel
• Multiple flexible low-power modes, including new compute clocking option which reduces dynamic power by placing peripherals in an asynchronous stop mode
• LPUART, SPI, I²C, ADC, DAC, LP timer and DMA support low-power mode operation without waking up the core

Memory

• Up to 32 KB flash with 64 byte flash cache, up to 4 KB RAM
• Security circuitry to prevent unauthorized access to RAM and flash contents
• 8 KB ROM and built-in boot loader simplifies the effort to program MCU and allows for easy flash upgrades

Performance

• ARM Cortex-M0+ core, 48 MHz core frequency over full voltage and temperature range (-40C to +105C)
• Bit manipulation engine for improved bit handling of peripheral modules
• Thumb instruction set combines high code density with 32-bit performance
• Up to 4-ch. DMA for peripheral and memory servicing with reduced CPU loading and faster system throughput
• Independent-clocked COP guards against clock skew or code runaway for fail-safe applications

Mixed-Signal

• 12-bit ADC with configurable resolution, sample time and conversion speed/power
• Integrated temperature sensor
• High-speed comparator with internal 6-bit DAC
• 12-bit DAC with DMA support

Timing and Control

• One 6-ch. and one 2-ch. 16-bit low-power timer PWM modules with DMA support
• 2-ch., 32-bit periodic interrupt timer provides time base for RTOS task schedule or trigger source for ADC conversion
• Low-power timer allows operation in all power modes except for VLLS0
• Real-time clock with calendar

Human-Machine Interface

• Capacitive touch sense interface supports up to 16 external electrodes and DMA data transfer
• GPIO with pin interrupt support, DMA request capability and other pin control options

Connectivity and Communications

• I²C with DMA support, up to 100 kbps and compatible with SMBus V2 features
• LPUART and SPI with DMA support
