Product details
Overview
S6E1A12C0AGN20000 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 12-bit ADC (8 channels), LIN 2.1/UART/I²C/CSIO interfaces, RTC, QPRC, and dual watchdog timers. It operates up to 40 MHz at 2.7–5.5 V and targets low-power embedded control in industrial sensors and motor drive subsystems.
For engineers reviewing the S6E1A12C0AGN20000 datasheet, S6E1A12C0AGN20000 pinout, S6E1A12C0AGN20000 application, or S6E1A12C0AGN20000 equivalent, key selection criteria include its 48-pin LQFP package, 37 fast GPIOs with port relocation, 16-bit PWM/PPG timers, hardware watchdog clocked by 100 kHz CR oscillator, and 5 V-tolerant I/O capability on designated pins.
Technical Context
The S6E1A12C0AGN20000 implements a Cortex-M0+ r0p1 core with NVIC supporting 32 peripheral interrupts and 4 priority levels, plus SysTick and bit-band addressing compatible with Cortex-M3. Its clock system integrates five sources: main (4–40 MHz), sub (32.768 kHz), high-speed CR (4 MHz), low-speed CR (100 kHz), and main PLL.
Peripheral integration includes three multi-function serial channels (configurable as UART, CSIO, LIN, or I²C), a 12-bit successive-approximation ADC with 0.8 µs conversion time at 5 V, quadrature position/revolution counter with AIN/BIN/ZIN edge configuration, and four base timer channels supporting PWM, PPG, reload, and PWC modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, r0p1 revision, 40 MHz max operation - enables deterministic real-time control with low gate count and power. |
| Memory | 88 KB Flash (0-wait read, code protection), 6 KB SRAM - sufficient for firmware + data buffers in standalone sensor nodes. |
| ADC | 12-bit SAR, 8-channel, 0.8 µs @ 5 V - supports fast analog monitoring of motor current or temperature with scan/priority modes. |
| Serial Interfaces | 3x configurable channels (UART/CSIO/LIN/I²C), each with 128-byte FIFO - enables concurrent LIN bus master and UART debug without CPU overhead. |
| Timers | 4x base timers (16/32-bit), dual 32/16-bit down counters, QPRC (16-bit pos/rev), 3x MFT free-run timers - meets motor commutation, encoder feedback, and RTC wake-up timing requirements. |
| I/O & Power | 37 fast GPIOs (1-cycle access), 5 V-tolerant on select pins, 2.7–5.5 V supply - simplifies interface to legacy 5 V logic and reduces level-shifter count. |
| Low-Power Modes | 4 modes (SLEEP/TIMER/RTC/STOP); hardware watchdog active in all except RTC/STOP - enables battery-powered operation with sub-µA retention in STOP mode. |
Pinout & Package
Package: 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual VCC pins (Pins 1, 48) and multiple VSS (Pins 2, 24, 47) ensure stable core/peripheral rail decoupling. |
| P00–P07, P10–P17, P20–P27, P30–P37 | General-purpose I/O | 37 total fast GPIOs; port relocation allows peripheral function mapping to avoid PCB routing conflicts. |
| XTAL1 / XTAL2 | Main clock oscillator input/output | Supports 4–40 MHz crystal; internal load caps reduce external component count. |
| OSC32K / OSC32KOUT | Sub-clock oscillator input/output | Drives 32.768 kHz crystal for RTC and low-power wake-up timing. |
| SWDIO / SWCLK | Serial Wire Debug interface | Enables non-intrusive debugging and flash programming using standard ARM SW-DP protocol. |
| AIN / BIN / ZIN | Quadrature encoder inputs | Dedicated edge-configurable inputs for position/speed feedback in BLDC/PMSM motor control. |
Key Features
| Feature | Design Value |
|---|---|
| LIN 2.1 support with variable break field (13–16 bits) | Enables direct integration into automotive body electronics networks without external LIN transceiver. |
| Hardware watchdog clocked by 100 kHz CR oscillator | Remains operational in all low-power modes except RTC/STOP, ensuring fail-safe recovery during sleep states. |
| Port relocation function | Allows dynamic assignment of UART, I²C, or timer outputs to alternate pins-reduces PCB redesign risk. |
| Real-time Clock with leap-year correction | Maintains accurate calendar time across decades without host software intervention or external RTC chip. |
| Micro Trace Buffer (MTB) | On-chip instruction trace buffer enables cycle-accurate execution analysis without external trace pins or bandwidth overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S6E1B12C0AGN20000 | Same core, package, and peripheral set; differs only in Flash size (128 KB vs. 88 KB) and SRAM (12 KB vs. 6 KB). | Preferred where larger firmware image or RTOS heap space is required; no change to pinout or driver compatibility. | Select when future firmware expansion or OTA update partitioning is needed. |
| MB9BF124RPMC-G-SNE2 | Fujitsu FM4 Cortex-M4F core (120 MHz), 256 KB Flash, 64 KB SRAM, but lacks native LIN 2.1 and QPRC; requires external transceiver and encoder IC. | Higher performance for complex algorithms (e.g., FOC with observer), but increases BOM cost and layout complexity. | Choose only if computational throughput exceeds Cortex-M0+ limits and LIN/QPRC can be implemented externally. |
Compared with S6E1B12C0AGN20000, this part trades memory headroom for lower cost and footprint; versus MB9BF124RPMC-G-SNE2, it delivers optimized LIN/motor control integration at lower power and simpler design, albeit with less raw compute.
