Infineon Technologies S6E1C12D0AGV20000

Overview

S6E1C12D0AGV20000 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M0+ microcontroller with 128 KB Flash, 16 KB SRAM, 40.8 MHz max CPU frequency, 1.65–3.6 V operation, and integrated 12-bit 1-Msps ADC with 8-channel mux - deployed in battery-powered IoT sensors and smart home appliance controllers.

For engineers reviewing the S6E1C12D0AGV20000 datasheet, S6E1C12D0AGV20000 pinout, S6E1C12D0AGV20000 application, or S6E1C12D0AGV20000 equivalent, key selection criteria include ultra-low active power (40 µA/MHz), six low-power modes (down to 0.6 µA standby), USB 2.0 device/host support, and dual I2S interfaces for audio edge nodes.

Technical Context

The S6E1C12D0AGV20000 implements an ARM Cortex-M0+ core with nested vectored interrupt controller (NVIC) supporting 24 peripheral interrupts and 4 priority levels, plus a 24-bit SysTick timer for RTOS scheduling. It integrates a Descriptor System Transfer Controller (DSTC) for autonomous peripheral-to-memory transfers without CPU intervention.

Its clock system includes a main PLL (configurable with external crystal or internal 8 MHz CR oscillator), sub-clock oscillator, and dual CR oscillators (8 MHz ±1.5%, 100 kHz ±10%). The device supports SW-DP debug interface and features hardware CRC acceleration and IEC60730 Class B self-test library compatibility.

FAQ

What is the maximum operating frequency and voltage range for S6E1C12D0AGV20000?

The S6E1C12D0AGV20000 operates up to 40.8 MHz across a 1.65 V to 3.6 V supply range. Its internal PLL supports both external crystal (1–20 MHz) and internal 8 MHz CR oscillator as clock sources, with guaranteed timing margins per datasheet Section 11.4.4–11.4.5. Voltage tolerance is validated down to 1.65 V at full frequency, enabling direct Li-ion or two-AA battery operation without regulators.

Does S6E1C12D0AGV20000 support USB device and host modes simultaneously?

No - the integrated USB 2.0 peripheral supports either device or host mode per boot configuration, not concurrent operation. Mode selection is controlled by the UHCONX0 register and requires firmware reinitialization to switch. Dual-role operation is not implemented in hardware; external USB switch ICs or companion controllers are needed for true OTG functionality.

How many ADC channels are accessible in the 64-pin LQFP package?

All 8 ADC input channels (AN0–AN7) are available on the 64-pin LQFP package (LQD064). These share pins with GPIO ports P0x–P4x and are fully functional when configured via the ADTG register. No channel is disabled due to pin count limitations - unlike the 32-pin variants which support only 6 channels.

Is IEC60730 Class B compliance supported out-of-the-box?

Yes - the S6E1C12D0AGV20000 includes hardware features required for Class B (e.g., clock supervision, RAM/Flash CRC, watchdog timers) and ships with AN205411-compliant self-test library source code. However, final certification requires customer implementation of test routines, fault injection validation, and documentation per IEC60730-1 Annex H - no pre-certified firmware image is provided.
