Infineon Technologies S6E1C12B0AGN20000

Overview

S6E1C12B0AGN20000 from Cypress Semiconductor (now Infineon) is a 32-bit ARM® Cortex®-M0+ microcontroller with 128 KB on-chip Flash, 16 KB SRAM, 40.8 MHz max CPU frequency, 12-bit ADC (2.0 µs conversion), and integrated peripherals including UART, SPI (CSIO), I²C, I²S, HDMI-CEC, Smart Card, RTC, and DSTC-designed for low-power embedded control in industrial sensors and metering systems.

For engineers reviewing the S6E1C12B0AGN20000 datasheet, S6E1C12B0AGN20000 pinout, S6E1C12B0AGN20000 application, or S6E1C12B0AGN20000 equivalent, key selection criteria include Deep Standby mode RAM retention (4 KB), 5 V-tolerant GPIOs, hardware watchdog clocked by 100 kHz CR oscillator, and ISO7816-3 Smart Card interface compliance.

Technical Context

The S6E1C12B0AGN20000 implements the ARM Cortex-M0+ r0p1 core with NVIC supporting 24 peripheral interrupts and 4 priority levels, plus SysTick and bit-band addressing compatible with Cortex-M3. It integrates a Descriptor System Transfer Controller (DSTC) with 64 channels for CPU-offload data movement between memory and peripherals.

Its clock system supports five sources: external 8–48 MHz main oscillator, 32.768 kHz sub-clock, built-in 8 MHz/100 kHz CR oscillators, and main PLL (75–150 MHz output). Power management includes six low-power modes-Deep Standby RTC and Deep Standby Stop-with configurable RAM retention and wake-up via Watch Counter or external interrupt.

Key Specifications

Pinout & Package

Manufacturer

Cypress Semiconductor was acquired by Infineon Technologies in 2020; Infineon now owns and supports the FM0+ microcontroller family, delivering high-integration, low-power MCUs for industrial and consumer applications.

The S6E1C1 Series belongs to Infineon's FM0+ family-designed specifically for cost-sensitive, ultra-low-power embedded control where peripheral integration (CEC, Smart Card, DSTC) reduces external component count and board space.

FAQ

Is S6E1C12B0AGN20000 still in active production?

Yes. Although the original spec document (002-00234) is marked obsolete, Infineon continues manufacturing and supporting the S6E1C12B0AGN20000 under replacement spec 002-00233. Full datasheet, errata, and software tools remain available on Infineon's official product page for FM0+ devices.

What package variants are available for this part number?

S6E1C12B0AGN20000 is exclusively offered in the 64-pin LQFP package (10 × 10 mm, 0.5 mm pitch, GN20000 suffix). No QFN, BGA, or smaller-footprint variants exist for this specific configuration-pin count and peripheral set require the full 64-pin layout per the FM0+ family architecture.

Does this MCU support USB device functionality?

No. The S6E1C12B0AGN20000 does not include a USB PHY or USB controller. Its communication interfaces are limited to UART, CSIO (SPI), I²C, I²S, HDMI-CEC, and Smart Card. USB connectivity requires external bridge ICs or migration to Infineon's XMC4000 or PSoC families.

Can the 4 KB of SRAM be retained in Deep Standby Stop mode?

Yes-Deep Standby Stop mode supports configurable RAM retention: users may select either full 16 KB retention or reduced 4 KB retention (the same block preserved in Deep Standby RTC) to minimize leakage current. This setting is controlled via the SYSCON register's DSSTOPCR bits per the FM0+ Peripheral Manual.
