Infineon Technologies SAK-CIC751-EOM16T BA

Overview

SAK-CIC751-EOM16T BA from Infineon Technologies is a companion IC designed exclusively to extend 5 V analog-to-digital conversion capability to AUDO-NG 32-bit microcontrollers via MLI or SSC interfaces. It features a 16-channel 5 V ADC, internal low-power oscillator, flexible clocking (up to 40 MHz system frequency), and separate ADC supply rail for precision measurement in automotive powertrain control units.

For engineers reviewing the SAK-CIC751-EOM16T BA datasheet, SAK-CIC751-EOM16T BA pinout, SAK-CIC751-EOM16T BA application, or SAK-CIC751-EOM16T BA equivalent, this device serves as a dedicated ADC co-processor with dual-voltage I/O (3.3 V/5.0 V), crossbar bus architecture, and DMA-assisted data transfer-critical for real-time sensor acquisition in safety-critical engine management systems.

Technical Context

The CIC751 operates as a slave peripheral, not a standalone MCU, relying on host AUDO-NG controllers for instruction execution and memory management. Its functional core comprises a 16-channel 5 V ADC with configurable sampling, an MLI interface supporting 5 V/3.3 V signaling, and an SPI-compatible SSC interface with programmable timing.

Internal timing is governed by a prescaler and PLL subsystem enabling precise synchronization with host clocks; power sequencing mandates strict ordering between VDDA (ADC supply), VDDP (pad supply), and VDDC (core supply) to prevent latch-up or conversion error.

FAQ

What is the primary function of the SAK-CIC751-EOM16T BA?

The SAK-CIC751-EOM16T BA is a dedicated companion IC that provides 5 V analog-to-digital conversion capability to Infineon's AUDO-NG 32-bit microcontrollers. It does not execute code or manage memory; instead, it handles ADC acquisition, timing, and data transfer via MLI or SSC interfaces under host MCU control.

Does the CIC751 require an external crystal or oscillator?

No. The CIC751 integrates a low-power on-chip oscillator for basic timing and supports external clock injection via the MLI interface from the host AUDO-NG MCU. No external crystal is required unless system-level jitter specifications demand higher stability than the internal oscillator provides.

Can the SAK-CIC751-EOM16T BA operate with a 3.3 V core supply?

Yes. While its ADC section requires 5.0 V (VDDA), the core and I/O sections (VDDC/VDDP) are rated for 3.3 V operation per datasheet Section 4.2. This allows direct integration with 3.3 V AUDO-NG derivatives while retaining 5 V sensor compatibility through the dedicated analog rail.

Is the MLI interface compatible with non-Infineon microcontrollers?

No. The Micro Link Interface (MLI) is a proprietary Infineon protocol defined only for use between CIC751 and AUDO-NG family MCUs. It is not electrically or logically compatible with standard interfaces like SPI, I²C, or UART, and lacks documentation for third-party implementation.
