Product details
Overview
TC1736128F80HLAAKXQMA1 from Infineon Technologies is a 32-bit TriCore V1.3.1 single-chip microcontroller featuring an 80 MHz CPU, 1 MB program flash (PFlash), 32 KB data flash (DFlash), and dual 12-bit ADCs with 24 analog inputs. It integrates MultiCAN (2 nodes, 64 message objects), GPTA timer array, and FADC with 262.5 ns conversion time-designed for automotive powertrain and chassis control units requiring deterministic real-time response.
For engineers reviewing the TC1736128F80HLAAKXQMA1 datasheet, TC1736128F80HLAAKXQMA1 pinout, TC1736128F80HLAAKXQMA1 application, or TC1736128F80HLAAKXQMA1 equivalent, this page delivers verified electrical parameters, validated package mapping (LQFP-176), confirmed peripheral timing (PLL lock time ≤ 100 µs, CAN bit rate up to 1 Mbps), and functional alternatives aligned to TriCore-based ECU architectures.
Technical Context
The TC1736128F80HLAAKXQMA1 implements a super-scalar TriCore V1.3.1 CPU with 4-stage pipeline, single-precision FPU, and hardware-supported DSP instructions. Its memory subsystem includes 36 KB LDRAM, 8 KB SPRAM, and configurable 8 KB instruction cache-enabling tight-loop execution in motor control algorithms.
On-chip peripherals are tightly coupled via 64-bit local memory buses and 32-bit system peripheral bus (SPB). The MultiCAN module supports concurrent CAN FD-ready message handling with FIFO buffering and gateway routing, while the FADC achieves 21-cycle conversion at 80 MHz clock-critical for high-resolution current sensing in inverter gate drivers.

FAQ
What is the maximum operating temperature range for TC1736128F80HLAAKXQMA1?
The device is qualified for continuous operation from –40°C to +125°C ambient temperature, with all electrical parameters-including 80 MHz CPU frequency, ADC linearity, and CAN bit timing-guaranteed across this full range per Data Sheet V1.1 Section 5.1.4. Thermal resistance θJA is 28.5 K/W for LQFP-176 package mounted on 4-layer PCB with 2 oz copper.
Does TC1736128F80HLAAKXQMA1 support CAN FD?
No. The MultiCAN module supports Classical CAN only, with bit rates up to 1 Mbps and 64 message objects. CAN FD capability was introduced in later TriCore generations (e.g., TC275). This part implements ISO 11898-1:2003 compliant CAN protocol with hardware message filtering and FIFO buffering-but lacks FD frame format support or increased data field length.
How is flash programming performed on TC1736128F80HLAAKXQMA1?
Programming uses the on-chip BootROM (16 KB) and standard ASC or DAP interface. The ROM contains a certified bootloader supporting PFlash/DFlash erase/write via UART or JTAG-DAP, with checksum verification and sector protection keys. No external programmer is needed-field updates are performed using Infineon's MemTool or compatible AURIX™ development tools.
Is TC1736128F80HLAAKXQMA1 qualified to AEC-Q100?
Yes. The device is AEC-Q100 Grade 1 qualified (–40°C to +125°C), with full qualification test reports covering HTOL, ESD, latch-up, and temperature cycling. This is documented in Infineon's quality declaration QD-TC1736-V1.1 (Section 5.4.4) and referenced in the device's ordering code suffix "QMA1", which denotes automotive qualification.
