Infineon Technologies S6E1C11B0AGN20000

Overview

S6E1C11B0AGN20000 from Cypress Semiconductor 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 sensor nodes.

For engineers reviewing the S6E1C11B0AGN20000 datasheet, S6E1C11B0AGN20000 pinout, S6E1C11B0AGN20000 application, or S6E1C11B0AGN20000 equivalent, key selection criteria include Deep Standby RTC mode with 4 KB SRAM retention, 5 V-tolerant GPIOs, hardware CRC16/32 acceleration, dual watchdog timers (HW + SW), and 64-pin LQFP package with port relocation support.

Technical Context

The S6E1C11B0AGN20000 implements an ARM Cortex-M0+ core (r0p1) with NVIC supporting 24 peripheral interrupts and 4 priority levels, coupled with a 24-bit SysTick timer for RTOS scheduling. It integrates a Descriptor-based Data Transfer Controller (DSTC) with 64 channels for CPU-offload DMA transfers between memory and peripherals like ADC, UART, or CSIO.

Clock architecture includes five sources: external main clock (8–48 MHz), sub-clock (32.768 kHz), built-in high-speed CR (8 MHz), low-speed CR (100 kHz), and main PLL (75–150 MHz output). Power management supports six low-power modes-including Deep Standby Stop with configurable RAM retention-and features LVD1/LVD2 voltage monitoring and Clock Supervisor (CSV) for external clock failure detection.

FAQ

What is the maximum operating frequency and core revision of the S6E1C11B0AGN20000?

The S6E1C11B0AGN20000 operates at up to 40.8 MHz and implements the ARM Cortex-M0+ processor with revision r0p1. This core version supports Thumb-2 instruction set, NVIC with 4 priority levels, and SysTick timer-delivering deterministic interrupt latency and efficient code density for resource-constrained firmware.

Does this MCU support hardware flow control on UART, and which channel supports it?

No, the S6E1C11B0AGN20000 does not support hardware flow control (RTS/CTS) on any UART channel. Per the official datasheet (Rev. *C, page 2), hardware flow control is explicitly excluded for S6E1C11B0A and S6E1C11C0A variants. Only S6E1C12B0A/S6E1C12C0A models include this feature on UART channel 4.

How much SRAM is retained in Deep Standby RTC mode, and what is the voltage range?

In Deep Standby RTC mode, 4 KB of the 16 KB on-chip SRAM is retained while the rest is powered down. The device operates across a 1.65 V to 3.6 V supply range, with LVD2 configured to trigger auto-reset if VCC drops below the selected threshold-ensuring reliable state preservation during brown-out conditions.

Is the S6E1C11B0AGN20000 pin-compatible with other S6E1C1 series variants?

Yes, all S6E1C1x variants in the 64-pin LQFP package-including S6E1C11B0A, S6E1C12B0A, S6E1C11C0A, and S6E1C12C0A-are pin-compatible. Differences lie in memory configuration (Flash/SRAM size), peripheral enablement (e.g., UART flow control), and voltage grade (B = 1.65–3.6 V, C = 2.7–3.6 V), allowing drop-in replacement within same package variant.
