Infineon Technologies FT1162128F66HLAAXP

Overview

FT1162128F66HLAAXP from Infineon Technologies is a 32-bit TriCore v1.3 single-chip microcontroller featuring a 66 MHz CPU, 1024 KB program flash, 32 KB SRAM, and integrated MultiCAN (2 nodes), ASC, SSC, MLI, GPTA, ADC (16-channel, 12-bit), and FADC (2-channel, 10-bit, 318.2 ns min conversion). It targets automotive powertrain and chassis control units requiring deterministic real-time response.

For engineers reviewing the FT1162128F66HLAAXP datasheet, FT1162128F66HLAAXP pinout, FT1162128F66HLAAXP application, or FT1162128F66HLAAXP equivalent, key selection criteria include its 1.5 V core / 3.3 V I/O supply, -40°C to +85°C industrial temperature range, PG-LQFP-176 package, and TriCore architecture support for safety-critical ASIL-B software execution.

Technical Context

The FT1162128F66HLAAXP implements a super-scalar TriCore v1.3 CPU with 4-stage pipeline, single-precision FPU, and hardware bit manipulation-enabling cycle-accurate control loop execution in motor control and engine management. Its memory subsystem includes 64-bit LMB to Flash, SPB interconnect, and memory protection unit supporting secure partitioning of code and data spaces.

Peripheral timing is tightly synchronized via the on-chip clock generation unit with PLL, delivering stable 66 MHz core clock and programmable peripheral clocks for ASC (baudrate generator), SSC (master mode), and MLI (119 ns t31 timing limit). The 255-level priority interrupt system ensures sub-microsecond latency for critical CAN and ADC events.
