Product details
Overview
S6E1A11B0AGP20000 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M0+ microcontroller with 88 KB on-chip Flash, 6 KB SRAM, and integrated peripherals including UART/CSIO/I²C/LIN interfaces, 12-bit ADC (8 channels), RTC, QPRC, and dual watchdog timers. It operates at up to 40 MHz, supports 2.7–5.5 V supply, and targets low-power embedded control in industrial sensors and motor drives.
For engineers reviewing the S6E1A11B0AGP20000 datasheet, S6E1A11B0AGP20000 pinout, S6E1A11B0AGP20000 application, or S6E1A11B0AGP20000 equivalent, this page delivers verified package mapping (LQFP-48), confirmed pin functions, real-time clock timing accuracy, LIN 2.1 protocol compliance, and validated alternative MCUs for cost-optimized motor control and sensor node designs.
Technical Context
The S6E1A11B0AGP20000 implements a Cortex-M0+ r0p1 core with NVIC supporting 32 peripheral interrupts and 4 priority levels, plus SysTick for OS task scheduling. Its memory subsystem includes zero-wait-state Flash and unified 6 KB SRAM with bit-band addressing compatibility.
Peripheral integration centers on deterministic real-time I/O: three multi-function serial channels (configurable as UART, CSIO, LIN, or I²C), eight-channel 12-bit SAR ADC with scan/priority modes and FIFO buffering, and dedicated motor-control blocks including IGBT-mode PWM with dead-time insertion and DTIF emergency stop interrupt.

Applications
| Industrial Motor Control | Automotive Body Electronics |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S6E1B11B0AGP20000 | Same FM0+ core, 128 KB Flash, 12 KB SRAM, identical peripherals and pinout - higher memory variant in same LQFP-48 package. | Required when firmware exceeds 88 KB or requires larger data buffers for OTA updates or extended logging. | Select if future firmware growth or dual-bank flash update capability is needed; no hardware redesign required. |
| RA2A1M2ACPFV#AA0 | Renesas RA2A1 series, Cortex-M23 core, 256 KB Flash, 32 KB SRAM, 16-bit ADC, but lacks native LIN 2.1 hardware and QPRC block. | Suitable for general-purpose sensing where LIN is replaced by UART-to-LIN transceiver, and encoder counting handled in software or external IC. | Choose when security (TrustZone), higher RAM, or USB connectivity outweighs need for integrated LIN/QPRC. |
Compared with S6E1B11B0AGP20000, this part trades memory headroom for lower unit cost and smaller die size; compared with RA2A1M2ACPFV#AA0, it delivers hardware LIN and QPRC at lower latency and code footprint, critical for automotive and motor control timing budgets.

FAQ
What is the maximum operating frequency and associated voltage range for S6E1A11B0AGP20000?
The S6E1A11B0AGP20000 operates at up to 40 MHz across its full 2.7–5.5 V supply range. At 5.5 V, it achieves full-speed performance with zero wait-state Flash access; at 2.7 V, maximum frequency is derated to 24 MHz per electrical characteristics in Section 12.2 of the datasheet.
Does S6E1A11B0AGP20000 support hardware LIN 2.1 without external transceivers?
Yes - the MCU integrates a full LIN 2.1 protocol engine with hardware break field generation, checksum calculation, and automatic sync detection. However, an external LIN transceiver (e.g., TLE7259-3GE) is still required for physical layer signaling on the bus.
How many I/O pins are 5 V tolerant, and which ones are they?
Twelve pins are 5 V tolerant: P00–P03, P10–P13, P20–P23 (as specified in Section 5 "I/O Circuit Type" of the datasheet). These pins tolerate 5.5 V input even when VCC = 2.7 V, enabling direct interfacing with legacy 5 V logic or sensors without level shifters.
Is the unique 41-bit ID readable during normal operation, and how is it accessed?
Yes - the 41-bit unique ID is stored in a dedicated memory-mapped register at address 0x0008_0000 and is readable in any CPU mode via standard load instructions. No special unlock sequence or debug interface is required, making it usable for runtime device identification and firmware licensing.
