Product details
Overview
S5LS20206ASPGEQQ1R from Texas Instruments is a safety-certified 16/32-bit RISC flash microcontroller featuring dual ARM® Cortex™-R4F CPUs in lockstep, 2MB Flash with ECC, 160KB SRAM with ECC, and operation up to 140 MHz. It delivers 224 DMIPS and integrates FlexRay, three CAN controllers (two with 64 mailboxes), two LIN/UART interfaces, and dual 12-bit MibADCs with 20 total input channels - deployed in automotive powertrain and chassis control units requiring ASIL-D compliance.
For engineers reviewing the S5LS20206ASPGEQQ1R datasheet, S5LS20206ASPGEQQ1R pinout, S5LS20206ASPGEQQ1R application, or S5LS20206ASPGEQQ1R equivalent, key selection criteria include lockstep CPU architecture, ECC-protected memory, FlexRay dual-channel support, 144-pin PGE package I/O count (68 peripheral pins), and qualification for automotive safety-critical systems per ISO 26262.
Technical Context
The S5LS20206ASPGEQQ1R implements a dual-core lockstep execution model with built-in CPU and memory BIST, Error Signaling Module (ESM) with dedicated error pin, and FMzPLL-based clock generation with oscillator monitoring.
