Product details
Overview
TC1798F512F300EPABKXUMA2 from Infineon Technologies is a 32-bit TriCore V1.6 super-scalar microcontroller with 300 MHz CPU clock, 4 MB program flash (ECC-protected), 192 KB data flash for EEPROM emulation, and integrated PCP2 peripheral control processor operating at 200 MHz. It targets automotive powertrain and chassis control systems requiring ASIL-D compliance support via Safe DMA and lockstep-capable peripherals.
For engineers reviewing the TC1798F512F300EPABKXUMA2 datasheet, TC1798F512F300EPABKXUMA2 pinout, TC1798F512F300EPABKXUMA2 application, or TC1798F512F300EPABKXUMA2 equivalent, key selection criteria include real-time interrupt latency (<100 ns), dual-core safety architecture, ERAY/ASC/SSC interface count, and flash ECC coverage for ISO 26262-compliant firmware storage.
Technical Context
The TC1798 integrates a TriCore V1.6 CPU with 6-stage pipeline and fully pipelined FPU, alongside a dedicated 200 MHz PCP2 coprocessor handling time-critical I/O tasks independently. Its memory subsystem includes 4 MB PFLASH with single-bit error correction and double-bit error detection, plus 192 KB DFLASH configured for wear-leveling EEPROM emulation.
Real-time performance is enabled by dual DMA controllers: a 16-channel general-purpose DMA and an 8-channel Safe DMA (SDMA) supporting lockstep operation and hardware-based error checking. The on-chip bus architecture features a 64-bit crossbar interconnect between CPU, flash, and SRAM, and a 32-bit System Peripheral Bus (SPB) connecting ASC, SSC, MSC, MLI, and ERAY peripherals.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC297TP128F300NACXUMA1 | TriCore V1.6.2 core, 300 MHz, 8 MB PFLASH, no ERAY - adds HSM security module and enhanced ADC resolution | Lacks ERAY but adds hardware security for OTA update signing - better suited for connected gateway ECUs than chassis control | Select when cryptographic acceleration and secure boot are prioritized over deterministic bus latency |
| SPC574SADPT2 | Power Architecture e200z4, 200 MHz, 2 MB flash, no PCP2 - includes SENT receiver and LIN PHYs | Optimized for sensor signal conditioning and LIN network bridging - lacks dual-core safety architecture and ERAY | Select for cost-sensitive body electronics where ASIL-B suffices and ERAY is unnecessary |
Compared with TC297TP128F300NACXUMA1 and SPC574SADPT2, the TC1798F512F300EPABKXUMA2 uniquely balances ERAY real-time determinism, dual-core safety partitioning, and mature toolchain support for legacy AUTOSAR 3.x powertrain stacks - making it optimal for retrofitting existing chassis control designs.

FAQ
What is the maximum operating junction temperature for TC1798F512F300EPABKXUMA2?
The device is rated for operation up to +150°C junction temperature, validated across the full industrial range (−40°C to +125°C ambient) with derated performance above +125°C ambient. Thermal design must maintain TJ ≤ 150°C under worst-case power dissipation conditions, including simultaneous CPU, PCP2, and peripheral activity.
Does TC1798F512F300EPABKXUMA2 support JTAG debugging in production environments?
Yes - it supports IEEE 1149.1-compliant JTAG with boundary scan and debug access port (DAP) for full visibility into CPU, PCP2, and memory states. Production programming uses DAP interface with secure authentication; JTAG remains accessible for post-deployment diagnostics when enabled in boot configuration.
How is EEPROM emulation implemented in the 192 KB DFLASH?
Infineon's DFLASH implements EEPROM emulation using a wear-leveling algorithm across 192 KB of sector-erasable flash, supporting byte-write access via dedicated firmware library (DAVE™). Each logical EEPROM address maps to rotating physical sectors, enabling >100,000 write cycles with guaranteed data retention for 10 years at +85°C.
Can the ERAY interface operate concurrently with ASC and SSC peripherals?
Yes - ERAY, ASC, and SSC operate independently on separate SPB bus segments with dedicated DMA channels. The 64-bit crossbar interconnect prevents bandwidth contention, allowing simultaneous ERAY frame transmission, ASC diagnostic polling, and SSC sensor data streaming without timing interference.
