• Full ARM ecosystem
Features
• ARM
®
Cortex™-M4 core
with DSP instruction support
• Up to 16-channel DMA.
Crossbar switch
• USB On-The-Go (Full Speed)
with device charger detect
Benefits
• Up to 100 MHz core supporting a broad range of processing bandwidth
needs
• Peripheral and memory servicing with reduced CPU loading. Concurrent
multi-master bus accesses for increased bus bandwidth
• Optimized charging current/time for portable USB devices, enabling
longer battery life. USB low-voltage regulator supplies up to 120 mA off
chip at 3.3 V to power external components from 5 V input
• LCD blink mode enables low average power while remaining in low-
power mode
• Segment fail detect guards against erroneous readouts and reduces
LCD test costs
• Frontplane/backplane reassignment provides pin-out flexibility, easing
PCB design and allows LCD configuration changes via firmware with no
hardware re-work
• Supports multiple 3 V and 5 V LCD panel sizes with fewer segments
(pins) than competitive controllers and no external components
• Unused LCD pins can be configured as other GPIO functions
• Enables the connection of external memories and peripherals
(e.g., graphics displays)
• Connection to SD, SDIO, MMC or CE-ATA cards for in-application
software upgrades, file systems or adding Wi-Fi
®
or Bluetooth
®
support
• General-purpose timers with hardware dead-time insertion and
quadrature decoding for motor control
• Infrared waveform generation for remote control applications
• ime base generation for RTOS task scheduler or trigger source for ADC
T
conversion and programmable delay block
• High reliability, fast access program memory with 4-level security
protection. Independent flash banks allow concurrent code execution
and firmware updating
• FlexMemory provides 32 byte–4 KB of user-segmentable byte write/
erase EEPROM. In addition, Flex NVM 32–256 KB for extra program
code, data or EEPROM backup
• Flexible, low-power LCD
controller with support for up
to 320 segments (40 x 8 or
44 x 4)
• FlexBus external bus
interface Secure digital host
controller
• Up to three FlexTimers with
up to 12 channels
• Carrier modulator transmitter
• 4-channel, 32-bit interrupt
• 64–512 KB flash.
Up to 128 KB of SRAM
• 32–256 KB FlexMemory
