Product details
Overview
XC2336B40F66LAAKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Family / Value Line, featuring a 80 MHz C166-compatible CPU with five-stage pipeline, 320 KB on-chip Flash memory, 16 KB PSRAM, and integrated MultiCAN Rev. 2.0B interface with 64 message objects across two CAN nodes. It operates from 3.0 V to 5.5 V and supports automotive-grade temperature range (–40°C to 125°C) in a 64-pin LQFP package.
For engineers reviewing the XC2336B40F66LAAKXUMA1 datasheet, XC2336B40F66LAAKXUMA1 pinout, XC2336B40F66LAAKXUMA1 application, or XC2336B40F66LAAKXUMA1 equivalent, key selection criteria include CAN node count, Flash memory size, real-time A/D conversion capability (10-bit, <1 µs), CCU6x PWM flexibility, and on-chip memory protection via ECC and MPU.
Technical Context
The XC2336B40F66LAAKXUMA1 implements a C166-derived 16/32-bit CPU core with zero-cycle jumps, one-cycle MAC, and background 32/16-bit division in 21 cycles. Its memory subsystem includes 320 KB Flash with ECC, 16 KB PSRAM, 16 KB DSRAM, 2 KB DPRAM, and 8 KB SBRAM - all mapped within a unified 16 MB linear address space.
Peripheral integration centers on deterministic real-time control: dual 10-bit A/D converters with broken-wire detection and preprocessing, two CCU6x units for complementary PWM generation, a 16-channel CC2 unit, GPT12E timer, RTC, system timer, and MultiCAN with gateway functionality across two physical CAN interfaces - all synchronized via shared clock domains and PEC-driven DMA.

Pinout & Package
XC2336B40F66LAAKXUMA1 is housed in a RoHS-compliant PG-LQFP-64-24 package (64-pin Low-Profile Quad Flat Package, 0.5 mm pitch, 10 mm × 10 mm body).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP / VSSP | Core power / ground | Dedicated 3.3 V supply pins for CPU and internal logic; decoupling required within 1 cm for stable 80 MHz operation. |
| VDDA / VSSA | Analog power / ground | Isolated 5 V analog supply domain for A/D converters and reference circuitry; prevents digital noise coupling into precision measurements. |

| ADCTRIG0 / ADCTRIG1 | Hardware A/D trigger inputs | Edge-triggered signals from timers or peripherals initiate simultaneous sampling on both ADCs - critical for motor phase current acquisition. |
| TRST / TCK / TMS / TDO / TDI | JTAG debug interface | Standard 5-pin JTAG port supporting boundary scan, flash programming, and real-time debugging via OCDS (On-Chip Debug Support). |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC2365B40F66LAAKXUMA1 | Same XC2000 Value Line architecture but with 512 KB Flash, 32 KB PSRAM, and enhanced CAN FD support (Rev. 2.0B + ISO 11898-1:2015). | Required for future-proof CAN FD adoption and larger AUTOSAR BSW stacks; not pin-compatible due to additional CAN FD signal pins. | Select when CAN FD migration path or >320 KB Flash for complex diagnostics/security features is needed. |
| TC234LP-32F200N AC | TriCore™ AURIX™ successor with lockstep dual-core, 200 MHz, 2 MB Flash, ASIL-D support, and integrated HSM - no C166 compatibility. | Targets ASIL-D functional safety systems (e.g., brake-by-wire); requires full toolchain and software re-architecture. | Select only for new designs requiring ISO 26262 ASIL-D compliance; not a drop-in replacement. |
Compared with XC2336B40F66LAAKXUMA1, XC2365B offers expanded memory and CAN FD readiness for incremental upgrades, while TC234LP represents a generational shift toward safety-certified multicore - making the XC2336B optimal for cost-sensitive, ASIL-B engine/body control where C166 legacy code reuse is critical.

FAQ
What is the maximum operating frequency and associated voltage range for XC2336B40F66LAAKXUMA1?
The device achieves 80 MHz CPU clock at 3.3 V nominal supply, with guaranteed operation from 3.0 V to 5.5 V. At 5.5 V, the maximum frequency remains 80 MHz; no higher frequency bin exists. The 12.5 ns instruction cycle time is specified across the full –40°C to +125°C temperature range under worst-case voltage and process corners.
Does XC2336B40F66LAAKXUMA1 support CAN FD or only classical CAN?
XC2336B40F66LAAKXUMA1 implements MultiCAN Rev. 2.0B only - supporting Classical CAN up to 1 Mbit/s with full CAN and basic CAN message objects. It does not include CAN FD physical layer support, arbitration bit rate switching, or FD frame format handling. CAN FD capability begins with later XC2365B derivatives.
How is Flash memory protected against corruption during power transitions?
Flash integrity is maintained via Error Correction Code (ECC) covering all program memory, detecting and correcting single-bit errors and detecting double-bit errors. Additionally, the hardware CRC checker can be configured to verify Flash sectors at boot or during runtime using user-defined polynomials - preventing execution of corrupted firmware.
Can the XC2336B40F66LAAKXUMA1 operate from a 5 V supply without level-shifting for its I/Os?
Yes - the device supports 5 V tolerant I/Os across all GPIO pins when VDDP is supplied at 3.3 V and VDDA at 5 V. This allows direct interfacing with 5 V sensors, actuators, and transceivers without external level shifters, provided the 5 V supply meets the specified ±5% tolerance and ripple limits per Section 4.1.1 of the datasheet.
