The AT32A403A Automotive series is based on ARM®Cortex®-M4 32-bit core operating at a frequency of up to 200 MHz. It
features a single-precision floating point unit (FPU), digital signal processor (DSP), rich peripherals, and flexible clock control mechanism,
bringing a high level of integration and a great competitive edge. Additionally, it embeds up to 1 MB Flash memory and 224
KB SRAM, particularly its zero-wait Flash access overtaking its counterparts in terms of performance.
The device operates in the temperature range of -40 ℃ to 105 ℃. It incorporates 8x UARTs, 2x CANs, IEEE-802.3 10/100Mbps Ethernet
port controller, particularly suitable for vehicle networking and in-car audio and video systems, and a USB interface supporting
crystal-less mode, enhancing reliability while at the same time lowering cost in the end products.
Reliability is considered one of the most important parts of automotive microcontrollers when it comes to ensuring safe driving in
harsh environments. As ARTERY’s first automotive MCU, the AT32A403A series, AEC-Q100 standards certified, is designed to
address a wide variety of applications with demanding safety requirements such as body control, ADAS, in-car multimedia system,
and BMS for new energy vehicles. Under AEC-Q100 standards, AT32A403A has successfully passed a series of reliability tests
including Accelerated Environment Stress Tests, Accelerated Lifetime Simulation Tests, Package Assembly Integrity Tests, and
Electrical Verification Tests.
