Product details
Overview
XC2388E136F128LRAAKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Premium Line, featuring a 128 MHz CPU with 7.8 ns instruction cycle, 1088 KB on-chip Flash, 24 KB DSRAM, and integrated MultiCAN (3 nodes), FlexRay (2 nodes), and dual 12-bit ADCs (24 channels, <1 µs conversion). It targets automotive powertrain and chassis control systems requiring ASIL-B compliance support.
For engineers reviewing the XC2388E136F128LRAAKXUMA1 datasheet, XC2388E136F128LRAAKXUMA1 pinout, XC2388E136F128LRAAKXUMA1 application, or XC2388E136F128LRAAKXUMA1 equivalent, key selection criteria include its 144-pin LQFP package, 3.0–5.5 V supply range, ECC-protected Flash/SRAM, hardware CRC checker, and dual-core-compatible debug via JTAG/DAP.
Technical Context
The XC2388E136F128LRAAKXUMA1 implements a C166-compatible 5-stage pipeline CPU with MPU, 16 KB ICache, and 16 MB linear address space. It integrates a Memory Protection Unit (MPU), Memory Checker (MCHK), and ECC for Flash and SRAM to support functional safety requirements in automotive ECUs.
Its peripheral set includes three independent CAN 2.0B controllers (64 message objects), two E-Ray FlexRay nodes compliant with Protocol Spec V2.1, and two synchronizable 12-bit ADCs with broken-wire detection and data preprocessing - all accessible via Peripheral Event Controller (PEC) for zero-latency DMA transfers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Clock | 128 MHz - enables 7.8 ns instruction cycle for deterministic real-time execution in engine control loops. |
| Flash Memory | 1088 KB - supports large AUTOSAR-compliant firmware images with ECC protection for ASIL-B applications. |
| SRAM | 24 KB DSRAM + 8 KB SBRAM + 2 KB DPRAM - provides segregated memory spaces for data, standby context, and dual-access peripherals. |
| ADC | Two 12-bit units, up to 24 channels, <1 µs conversion - enables simultaneous sampling of crankshaft, camshaft, and throttle position sensors. |
| CAN/FlexRay | 3 CAN nodes (64 message objects) + 2 FlexRay nodes (V2.1) - meets gateway and domain controller requirements in modern vehicle networks. |
| Package | PG-LQFP-144-23 - 144-pin green LQFP, 0.5 mm pitch, qualified for automotive temperature range (−40°C to +125°C). |
| Supply Voltage | 3.0 V to 5.5 V - compatible with 5 V legacy automotive subsystems and 3.3 V digital logic without level-shifting. |
Pinout & Package
XC2388E136F128LRAAKXUMA1 is housed in a PG-LQFP-144-23 package: 144-pin low-profile quad flat pack, 20 mm × 20 mm body, 0.5 mm lead pitch, RoHS-compliant green molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP / VSSP | Core Power / Ground | Dedicated 3.3 V supply pins for CPU and internal logic; decoupling required per datasheet layout guidelines. |
| VDDA / VSSA | Analog Power / Ground | Isolated 5 V analog supply domain for ADC reference and oscillator stability; must be filtered separately. |
| XTAL1 / XTAL2 | Crystal Oscillator Input/Output | Supports external crystal (1–20 MHz) or ceramic resonator; drives internal PLL for 128 MHz system clock. |
| TSINx / TSOUTx | FlexRay Transceiver Interface | Direct connection to external TJA1080 transceivers; supports dual-channel time-triggered communication with fault-tolerant bus access. |
| ADCTRIGx | ADC Trigger Input | Synchronizes ADC conversions with PWM edges or timer events - critical for motor current sampling in inverter control. |
| ERAYCLK | FlexRay Reference Clock Output | Provides 10 MHz clock to external transceivers; derived from internal PLL with jitter <100 ps RMS for protocol timing compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware CRC Checker | Programmable polynomial engine verifying Flash, SRAM, and peripheral register integrity - reduces software overhead for ISO 26262 FMEDA analysis. |
| Peripheral Event Controller (PEC) | 16-channel DMA controller with 24-bit addressing - enables zero-CPU-cycle data movement between ADC, CAN, and memory during real-time interrupts. |
| MultiCAN Gateway Mode | Message forwarding across 3 CAN nodes with configurable filtering and ID remapping - eliminates need for external gateway IC in body control modules. |
| Flexible PWM Generation (CCU6x) | Four independent CCU6 units supporting center-aligned, edge-aligned, and dead-time insertion - directly drives 3-phase inverter gate drivers in electric power steering. |
| On-Chip Debug Support | JTAG and Device Access Port (DAP) interfaces with OCDS - enables non-intrusive trace, breakpoint, and memory inspection without halting real-time operation. |

FAQ
What is the maximum operating temperature range for XC2388E136F128LRAAKXUMA1?
The device is qualified for −40°C to +125°C ambient temperature per AEC-Q100 Grade 2, with junction temperature limits defined in Section 4.1.2 of the datasheet. Thermal derating applies above 105°C ambient when operating at full 128 MHz clock with all peripherals active.
Does XC2388E136F128LRAAKXUMA1 support boot-from-Flash with secure startup?
Yes - it includes an on-chip bootstrap loader that verifies Flash checksums and supports user-defined startup sequences. The Memory Protection Unit (MPU) and ECC enable tamper-resistant initialization, though external HSM is required for cryptographic key management beyond basic integrity checks.
Can the FlexRay interface operate independently of the CAN modules?
Yes - FlexRay (E-Ray) and MultiCAN are fully independent peripherals sharing only the system bus and clock domain. Each has dedicated message RAM, DMA channels (via PEC), and interrupt vectors, allowing concurrent operation without resource contention.
Is there pin-to-pin compatibility between XC2388E136F128LRAAKXUMA1 and XC2387E variants?
No - while both use PG-LQFP-144-23, XC2387E lacks FlexRay and has fewer CAN nodes (2 vs. 3) and reduced Flash (768 KB vs. 1088 KB); pin functions differ in TQFP-144 mapping, particularly for ERAYCLK, TSIN/TSOUT, and additional CAN_TX/RX signals.
