The SAK-TC1796-256F150E-BD was developed for high-performance automotive and industrial real-time control.

Its TriCore™ architecture combines microcontroller, RISC and DSP functionality, while the integrated single-precision floating-point unit supports computationally intensive control algorithms.

The TC1796 operates at up to 150MHz and integrates 2MB Program Flash with ECC, 128KB Data Flash, DMA, multiple serial interfaces, timer modules and extensive analog resources.

Infineon's historical product documentation identifies the BD-Step automotive version as SP000228013 with an operating temperature range of -40°C to +125°C.

Key Specifications

Typical Applications

The TC1796 family was primarily aimed at high-performance automotive control systems, including:

• Engine control units

• Powertrain control

• Transmission control

• Chassis systems

• Automotive motor control

• Real-time actuator control

• Industrial embedded systems

The combination of high real-time performance, CAN communication, ADC resources and integrated DSP capability made the device suitable for complex automotive control algorithms.

SAK-TC1796-256F150E-BD Replacement

There is no simple assumption that a newer Infineon MCU will be a pin-compatible replacement for the TC1796.

For new designs, Infineon's TriCore architecture has evolved from the legacy AUDO family to newer AURIX™ TC2x, TC3x and TC4x generations.

However, migration requires evaluation of:

• CPU performance

• Flash and RAM requirements

• CAN interfaces

• ADC channels

• Timer resources

• Package and pinout

• Power supply architecture

• Existing TriCore software

• Functional safety requirements

For legacy boards where redesign is impractical, sourcing the original SAK-TC1796-256F150E-BD may remain the preferred option.

FAQ

Is SAK-TC1796-256F150E-BD obsolete?

Yes. The SAK-TC1796-256F150E-BD is currently listed as Obsolete / no longer manufactured.

What is the clock frequency of TC1796?

The device operates at up to 150MHz.

How much Flash does SAK-TC1796-256F150E-BD have?

It integrates 2MB of Program Flash with ECC, plus 128KB Data Flash for applications such as EEPROM emulation.

How many CAN interfaces does TC1796 provide?

The integrated MultiCAN module provides four CAN nodes and 128 assignable message objects.

What package does SAK-TC1796-256F150E-BD use?

The device uses a PG-BGA-416 surface-mount package.

Is AURIX a direct replacement for TC1796?

No. Newer AURIX™ MCUs continue the Infineon TriCore architecture, but they should not be considered pin-to-pin replacements. Hardware and software migration must be evaluated for each application.
