Product details
Overview
STA1295EOA from STMicroelectronics is an AEC-Q100 Grade 3 automotive infotainment processor featuring a dual-core ARM Cortex-A7 CPU up to 650 MHz, 768 KB embedded SRAM, 16/32-bit DDR3L interface at 660 MHz, and integrated ARM Cortex-M3 for secure CAN FD processing. It delivers 2500+ DMIPS and supports full-HD display audio systems with hardware-accelerated H.264 video decoding, OpenGL ES 2.0 graphics, and 6-channel audio DACs (103 dB SNR).
For engineers reviewing the STA1295EOA datasheet, STA1295EOA pinout, STA1295EOA application, or STA1295EOA equivalent, this page provides verified technical context, validated pin mapping, real-world use scenarios in cluster and head-unit designs, and confirmed alternative parts with documented functional differences.
Technical Context
The STA1295EOA integrates two tightly coupled ARM Cortex-A7 cores with 32 KB L1 instruction/data caches and 256 KB unified L2 cache, operating within a dedicated power domain and PLL for thermal-optimized performance. Its memory architecture includes 768 KB of cacheable 64-bit SRAM clocked at 200 MHz and a configurable DDR3L controller supporting 16/32-bit interfaces at 660 MHz.
The SoC embeds a dedicated ARM Cortex-M3 subsystem with 256 KB isolated memory and secured NOR interface, enabling real-time vehicle communication via one standard CAN and two CAN FD channels. Audio processing is handled by a 450 MIPS DSP with six stereo SRCs, six 103 dB SNR DACs, and dual mono ADCs for voice input (98 dB SNR), all routed through six I²S/multichannel audio ports.
