Product details
Overview
S5LS10106ASPGEQQ1 from Texas Instruments is a safety-certified 16/32-bit RISC Flash microcontroller featuring dual ARM® Cortex™-R4F CPUs in lockstep, 1-MB flash with ECC, 128-KB SRAM with ECC, and operation up to 140 MHz. It delivers >220 DMIPS for real-time control in automotive safety-critical systems such as electronic power steering and brake control units.
For engineers reviewing the S5LS10106ASPGEQQ1 datasheet, S5LS10106ASPGEQQ1 pinout, S5LS10106ASPGEQQ1 application, or S5LS10106ASPGEQQ1 equivalent, key selection considerations include ASIL-D compliance support, FlexRay/CAN/LIN interface count, NHET timer channel availability, and PGE package pin compatibility with legacy TMS570 designs.
Technical Context
The S5LS10106ASPGEQQ1 implements a lockstep dual-core architecture with CPU and memory BIST, ECC on flash and SRAM, and parity on peripheral memories - all coordinated by an Error Signaling Module (ESM) with dedicated error pin. Its FMzPLL-based clock system supports frequency modulation and includes oscillator/PLL monitoring for fail-safe timing integrity.
It integrates three MibSPI interfaces (128 buffers each, parity protected), two LIN/UART controllers, three DCAN controllers (two with 64 mailboxes, one with 32), and a dual-channel FlexRay controller with 8-KB message RAM. The 32-channel NHET and dual 12-bit MibADCs (24 total inputs, 64-word parity buffers each) are managed via dedicated transfer units with MPU protection.
