Infineon Technologies S6E1C32C0AGV20000

Overview

S6E1C32C0AGV20000 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M0+ microcontroller with 128 KB Flash, 16 KB SRAM, and 40.8 MHz max CPU frequency. It operates from 1.65 V to 3.6 V, delivers 40 µA/MHz active power, and integrates USB 2.0 (Host/Device), six MFS serial interfaces (configurable as UART/SPI/I²C/I²S), 12-bit 1-Msps ADC (8-channel), and hardware CRC accelerator - deployed in battery-powered IoT sensors and smart home appliance controllers.

For engineers reviewing the S6E1C32C0AGV20000 datasheet, S6E1C32C0AGV20000 pinout, S6E1C32C0AGV20000 application, or S6E1C32C0AGV20000 equivalent, key selection criteria include ultra-low-power standby (0.6 µA), fast wake-up (20 µs from Deep Standby), integrated USB PHY, and package-specific peripheral availability (e.g., I²S support only in 48-/64-pin variants).

Technical Context

The S6E1C32C0AGV20000 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. Its clock system includes dual oscillators: 8 MHz high-speed CR (±1% typical) and 100 kHz low-speed CR, plus main/sub crystal inputs and a main PLL supporting both crystal and CR sources.

Digital subsystem features include a 64-channel Descriptor System Transfer Controller (DSTC) for autonomous data movement, eight base timers (16-/32-bit), one dual timer, one watch counter, and real-time clock with calendar functions. Analog integration comprises a single 12-bit ADC with 8-channel multiplexer, programmable sampling time, and hardware trigger support from timers or external events.

FAQ

What is the maximum operating frequency and voltage range for the S6E1C32C0AGV20000?

The S6E1C32C0AGV20000 operates at up to 40.8 MHz with a supply voltage range of 1.65 V to 3.6 V. This range supports direct connection to single-cell Li-ion (3.0–3.6 V) or two-cell alkaline (2.4–3.2 V) batteries without external regulators, and its voltage tolerance ensures robust operation across battery discharge curves.

Does the S6E1C32C0AGV20000 include an integrated USB transceiver?

Yes, the S6E1C32C0AGV20000 integrates a full-speed USB 2.0 transceiver (PHY) supporting both host and device modes. It requires only external 27 Ω series resistors on D+/D− lines and TVS diodes for ESD protection - no external PHY IC is needed, reducing bill-of-materials and PCB complexity.

How many analog input channels does the onboard ADC support, and what is its resolution?

The onboard ADC is a single 12-bit successive-approximation converter with an 8-channel analog multiplexer (AN0–AN7). It achieves 1 Msps sampling rate with programmable sample-and-hold time, and supports hardware triggering from timers or external pins - enabling synchronized acquisition across multiple sensors.

What low-power modes are available, and what is the lowest achievable current draw?

The S6E1C32C0AGV20000 offers six low-power modes: Sleep, Timer, RTC, Stop, Deep Standby RTC, and Deep Standby Stop. In Deep Standby RTC mode with RAM retention disabled, it draws just 0.6 µA (typical) at 25°C - verified per datasheet Section 11.9 - making it suitable for decade-long deployments in environmental monitoring nodes.
