SAM HA1 A
LIN SBC + Cortex M0+-based MCU SiP
DATASHEET Description
The AtmelВ® SAM HA1 A is a low-power automotive system-in-package (SiP) product
series using the 32-bit ARMВ® CortexВ® M0+ processor featuring 48 pins with up to 64KB
of Flash, up to 2KB of read-while-write data flash, and up to 8KB of SRAM. The SAM
HA1 devices operate at a maximum frequency of 48MHz and reach
2.46 Coremark/MHz. They also include a LIN system basis chip (SBC) with a fully
integrated LIN transceiver designed in compliance with the LIN specifications 2.0, 2.1,
2.2, 2.2A and SAEJ2602-2, and a 3.3V/85mA voltage regulator.
Combining 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 bus.
The 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 interfaces.
The 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 …
