KS22 and KS20 Arm® Cortex®-M4 Microcontrollers with USB and Dual CAN
KS2X Receive alerts
The KS22 and KS20 MCUs are based on the ARM® Cortex®-M4 core with 120MHz with FPU, offering full-speed USB 2.0 OTG and dual CAN, in addition to other features like USB crystal-less functionality. These MCUs have 128 KB and 256 KB of flash, 64 KB SRAM as well as LQFP and QFN packages. They provide various levels of integration, with a rich suite of analog, communication, timing and control peripherals.
Product Details
Features
Ultra-Low-Power
- 10 low-power modes with power and clock gating for optimal peripheral activity and recovery times
- Full memory and analog operation down to 1.71 volts for extended battery life
- Low-leakage wake-up unit with up to eight internal modules and 16 pins as wake-up sources in low-leakage stop (LLS)/very low-leakage stop (VLLS) modes
- Low-power timer for continual system operation in reduced power state
Flash, SRAM and FlexMemory
- 128 KB-256 KB Flash. Fast access, high reliability with four-level security protection
- 64 KB SRAM
Performance
- ARM Cortex-M4 core + DSP. 120 MHz, single-cycle MAC, single instruction multiple data (SIMD) extensions, single precision floating point unit
- Up to 16-channel DMA for peripheral and memory servicing with reduced CPU loading and faster system throughput
- Cross bar switch enables concurrent multi-master bus accesses, increasing bus bandwidth
Mixed-Signal Capability
- 16-bit analog-to-digital converters (ADCs) with configurable resolution. Single or differential output mode operation for improved noise rejection. 500 ns conversion time achievable with programmable delay block triggering
- 12-bit digital-to-analog converters (DACs) for analog waveform generation for audio applications
- high-speed comparators providing fast and accurate motor over-current protection by driving PWMs to a safe state
Timing and Control
- Up tp 3 PWM and 1 TMR, can be operated in low-power mode
- Four-channel 32-bit periodic interrupt timer provides time base for RTOS task scheduler or trigger source for ADC conversion and programmable delay block
Human-Machine Intergace (HMI)
- Up to 66 controllable GPIO with pin interrupt support
Connectivity and Communications
- USB 2.0 On-The-Go (full-speed) with USB crystal-less functionality
- 1x LPUART that can be operated in low-power mode, 3x UART that support IrDA, one of them support ISO7816 smart card. Support different data side, format, and send/receive settings, compatible with multiple industry communication protocols
- 2x Inter-IC Sound (I2S) serial interface for audio system interfacing
- 2x CAN module for industrial network bridging
- 2x SPI
- 2x LPI2C, can be operated in low-power mode
- 1x FlexIO module that can be configured as different interface (e.g. UART/SPI/I2C/I2S), support operating in low-power mode
Reliability, Safety and Security
- Cyclic redundancy check engine validates memory contents and communication data, increasing system reliability
- Independent-clocked COP guards against clock skew or code runaway for fail-safe applications such as the IEC 60730 safety standard for household appliances
- External watchdog monitor drives output pin to safe state external components if watchdog event occurs
