Infineon Technologies SAK-TC1775-L40E BA

Overview

SAK-TC1775-L40E BA from Infineon Technologies is a 32-bit TriCore single-chip microcontroller with 40 MHz CPU clock, 72 KB on-chip SRAM, TwinCAN module, dual 16-channel ADCs (8/10/12-bit), and -40 °C to +125 °C operating range. It integrates GPTA, GPTU, ASC/SSC serial interfaces, FPI bus, and EBU for automotive powertrain control and industrial real-time I/O management.

For engineers reviewing the SAK-TC1775-L40E BA datasheet, SAK-TC1775-L40E BA pinout, SAK-TC1775-L40E BA application, or SAK-TC1775-L40E BA equivalent, key selection criteria include its dual CAN node architecture, 25 ns instruction cycle time, on-chip PCP for autonomous peripheral handling, and P-BGA-329 package thermal performance in high-temperature engine control units.

Technical Context

The TC1775 implements a dual-issue superscalar TriCore CPU with hardware context switching and 4-stage pipeline, enabling deterministic interrupt response under 100 ns. Its Peripheral Control Processor (PCP) executes low-level driver code independently using 20 KB dedicated memory, offloading the main core from time-critical I/O tasks like PWM generation and ADC sampling sequencing.

The integrated TwinCAN module features two synchronized CAN controllers sharing FIFO buffers and gateway logic, supporting concurrent CAN 2.0A/B message handling without CPU intervention. Clock generation includes a PLL with configurable multiplication factor and external crystal support (XTAL1–XTAL4), delivering stable 40 MHz fCPU while maintaining <±100 ppm jitter per Figure 31.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar 32-bit automotive microcontroller applications.

Compared with SAK-TC1775-L40E BA, the TC1766 offers lower cost and power but sacrifices critical automotive diagnostics (J1850) and CAN redundancy; the TC1797 adds Ethernet and memory headroom at higher BOM cost and thermal footprint-making the TC1775 the optimal balance for mid-tier powertrain and transmission control where J1850 compliance and dual-CAN are mandatory.

FAQ

What is the maximum ADC sampling rate supported by SAK-TC1775-L40E BA?

The TC1775 supports up to 1.25 MSps aggregate sampling rate across both ADC units. At 10-bit resolution, typical conversion time is 1.6 µs per channel (tC = 1.6 µs, fANA = 1–5 MHz per datasheet page 73). Simultaneous sampling on all 16 channels of ADC0 or ADC1 is achievable using hardware trigger synchronization from GPTA or timer events.

Does SAK-TC1775-L40E BA support JTAG boundary scan testing?

Yes, it supports IEEE 1149.1-compliant JTAG boundary scan via dedicated TMS, TDO, TDI, TCK, and TRST pins. The OCDS interface extends this with real-time trace and non-intrusive debugging, allowing full visibility into CPU register states and memory during live operation without halting execution.

Can the TwinCAN module operate in loopback mode for self-test?

Yes, each CAN node supports built-in loopback test mode where transmitted messages are internally routed back to the receive buffer without physical bus activity. This enables functional verification of CAN protocol stack and message filtering logic during startup or diagnostic routines without external hardware.

What is the purpose of the BRKIN and BRKOUT pins on SAK-TC1775-L40E BA?

BRKIN and BRKOUT are part of the On-Chip Debug Support (OCDS) system. BRKIN accepts external trigger signals to initiate trace capture or halt CPU execution; BRKOUT outputs synchronous event pulses (e.g., interrupt entry, memory access) for oscilloscope correlation or external logic analyzer triggering during development and validation.
