Key features

• Arm Cortex-M0+ processor (revision r0p1), running at frequencies of up to 15 MHz with single-cycle multiplier and fast single-cycle I/O port
• Arm Cortex-M0+ built-in Nested Vectored Interrupt Controller (NVIC)
• System tick timer
• AHB multilayer matrix
• Serial Wire Debug (SWD) with four break points and two watch points. JTAG boundary scan (BSDL) supported
• Up to 32 KB on-chip EEPROM based flash programming memory
• Code Read Protection (CRP)
• 4 KB SRAM
• Independent supplies on each package side permitting level-shifting signals from one off-chip voltage domain to another and/or interfacing directly to off-chip peripherals operating at different supply levels
• The switch matrix provides level shifter functionality to allow up to two selected signals to be routed from user-selected pins in one voltage domain to selected pins in the alternate domain. This feature can also be used on a single supply device if voltage level shifting is not required
