The SAM HA1 devices operate at a maximum frequency of 48 MHz and reach Coremark/MHz. They also include a LIN system basis chip (SBC) with a fully integrated LIN transceiver designed in compliance with the LIN specifications , , , and SAEJ2602-2, and a voltage a microcontroller, a LIN transceiver, and a voltage regulator makes it possible to develop simple but powerful slave nodes in LIN bus systems. Sleep mode and silent mode guarantee minimized current consumption even in the event of a floating or a short-circuited LIN series is qualified in compliance with AEC Q-100 ( 40 to +105 C Tcase).All devices in the product series include intelligent and flexible peripherals, the Atmel Event System for interperipheral signaling, and support for capacitive touch button, slider and wheel user Atmel SAM HA1 devices have the following features: In-system programmable Flash, eight-channel direct memory access (DMA) controller, 12-channel event system, programmable interrupt controller, 32 programmable I/O pins, 32-bit real-time clock and calendar, up to five 16-bit timer/counters (TC) and three 16-bit timer/counters for control (TCC), where each TC can be configured to perform frequency and waveform generation, accurate program execution timing or input capture with time and frequency measurement of digital signals.

2 The TCs can operate in 8- or 16-bit mode, selected TCs can be cascaded to form a 32-bit TC, and three timer/counters have extended functions optimized for motor, lighting and other control series provides up to five serial communication modules (SERCOM), with each configurable to act as a USART, UART, SPI, I2C up to , and LIN slave; up to 13-channel 350ksps 12-bit ADC with programmable gain and optional oversampling and decimation supporting up to 16-bit resolution, one 10-bit 350ksps DAC, up to two analog comparators with window mode, peripheral touch controller supporting buttons, sliders, wheels and proximity sensing; programmable window-watchdog timer, brown-out detector and power-on reset and two-pin serial wire debug (SWD) program and debug HA1 ALIN SBC + Cortex M0+-based MCU SiPDATASHEET2 Atmel | SMART sam ha1 a [DATASHEET]Atmel-9354A SAM-HA1-A_Datasheet 05/2016 All devices have accurate and low-power external and internal oscillators.

3 All oscillators can be used as a source for the system clock. Different clock domains can be independently configured to run at different frequencies, enabling power saving by running each peripheral at its optimal clock frequency, and thus maintaining a high CPU frequency while reducing power SAM HA1 devices offer different sleep modes according to the needs of the application. The LIN SBC offers sleep and silent mode and can shut down the voltage regulator to achieve very low power consumption. The microcontroller has two software-selectable sleep modes, idle and standby. In idle mode the CPU is stopped while all other functions can be kept running. In standby all clocks and functions are stopped except those selected to continue running. The device supports SleepWalking. SleepWalking allows peripherals to wake up from sleep based on predefined conditions, allowing the CPU to wake up only when needed, , when a threshold is crossed or a result is ready.

4 The Peripheral Event System supports synchronous and asynchronous events, allowing peripherals to receive, respond to and send events even in standby Flash program memory can be reprogrammed in-system through the SWD interface. The same interface can be used for non-intrusive on-chip application code debugging. A boot loader running in the device can use any communication interface to download and upgrade the application program in the Flash SAM HA1 devices are supported by a complete suite of program and system development tools, including C compilers, macro assemblers, program debugger/simulators, programmers and evaluation Cortex-M0+ CPU running at up to 48 MHzzSingle-cycle hardware multiplierzMicro trace bufferzMemoriesz16/32/64KB in-system self-programmable Flashz4/4/8KB SRAM read-while-write (RWW) Flash sectionzSystemzPower-on reset (POR) and brown-out detection (BOD)zInternal and external clock options with 48 MHz digital frequency-locked loop (DFLL48M) and 48 MHz to 96 MHz fractional digital phase-locked loop (FDPLL96M)zExternal interrupt controller (EIC)zUp to 14 external interruptszOne non-maskable interruptzTwo-pin serial wire debug (SWD)
