Product details
Overview
CY9AF112LAPMC-GNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 128 KB on-chip Flash, 16 KB SRAM, 80-pin LQFP package, 40 MHz max operating frequency, and integrated motor control peripherals including 8-channel Base Timers, 2-unit MF-Timer, and 12-channel 12-bit ADC. It targets cost-sensitive industrial motor drives and embedded control systems requiring LIN, UART, I²C, and CSIO interfaces.
For engineers reviewing the CY9AF112LAPMC-GNE2 datasheet, CY9AF112LAPMC-GNE2 pinout, CY9AF112LAPMC-GNE2 application, or CY9AF112LAPMC-GNE2 equivalent, key selection criteria include external bus interface support (absent in this variant), 83 GPIO capability in 100-pin variants versus 66 in this 80-pin LQFP, hardware flow control exclusion (ch.4–7 only), and dual watchdog (HW + SW) with LVD1/LVD2 voltage monitoring.
Technical Context
This MCU implements the Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer for RTOS scheduling. Its memory subsystem includes two independent SRAM banks (SRAM0/SRAM1), each 16 KB, connected to I-code/D-code and system buses respectively for concurrent instruction/data access.
The peripheral set is optimized for real-time motor control: Base Timers support PWM/PPG/PWC modes; QPRC units decode quadrature encoder signals; MF-Timers provide input capture, output compare, and A/D activation triggers; and the 12-channel 12-bit ADC achieves 1.0 μs conversion at 5 V with FIFO-based scanning and 2-level priority handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time execution with Thumb-2 instruction set and low-latency interrupt response. |
| Flash Memory | 128 KB, 0-wait-state read - supports fast code execution without cache penalties in cost-constrained designs. |
| SRAM | 16 KB total (SRAM0 + SRAM1), split-bus architecture - allows simultaneous CPU fetch and DMA access to avoid bus contention. |
| ADC | 12-bit SAR, 12 channels, 1.0 μs @5 V - delivers high-resolution analog sensing for motor current/voltage feedback loops. |
| Timers | 8-channel Base Timer + 2-unit MF-Timer + 2×QPRC - provides full waveform generation, encoder position tracking, and event-triggered A/D sampling. |
| Communication | 8-channel multi-function serial interface (UART/CSIO/LIN/I²C), 4 with 16×9-bit FIFO - ensures robust protocol handling with minimal CPU overhead for LIN 2.1 master/slave and UART flow control (excluded on ch.0–3). |
| Power Range | 2.7 V to 5.5 V operation - enables direct interfacing with 3.3 V and 5 V logic domains without level shifters. |
Pinout & Package
Package: 80-pin LQFP (LQG080, 0.65 mm pitch), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P09 | General-purpose I/O / Trace / SWD | Support debug via SWJ-DP (TCK/TMS/TDI/TDO/SWCLK/SWDIO); TRSTX enables JTAG reset; TRACE pins enable real-time instruction trace. |
| P20, P50–P51 | External interrupt / Quadrature inputs | INT00_0/INT01_0 accept asynchronous wake-up events; AIN0_2/BIN0_2/ZIN0_2 feed QPRC for encoder position decoding. |
| P60–P63 | Serial interface / External bus signals | SIN5_0/SOT5_0/SCK5_0 implement UART/CSIO/LIN on ch.5; MRDY_1/MWEX_1 manage external memory wait states (not used in CY9AF112LA). |
| VCC, VSS | Power supply / Ground | Dual VCC pins (pins 1, 75, 97) and multiple VSS (pins 2, 74, 96) ensure stable power delivery and noise suppression across high-speed digital blocks. |
Key Features
| Feature | Design Value |
|---|---|
| Port Relocate Function | Permits dynamic assignment of peripheral functions (e.g., UART, LIN) to alternate GPIO pins via EPFR registers-enables flexible PCB layout without hardware redesign. |
| CRC Accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 computation offloads integrity checks from CPU-reduces firmware overhead for communication frame validation and flash data verification. |
| Clock Supervisor (CSV) | Monitors external clock stability using internal CR oscillators-asserts reset on clock stop or frequency anomaly, ensuring fail-safe operation in safety-critical motor control. |
| Low-Voltage Detection | LVD1 triggers interrupt for software recovery; LVD2 forces automatic reset below threshold-prevents erratic behavior during brown-out conditions in industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY9AF114LAPMC-GNE2 | 256 KB Flash, 32 KB SRAM, 100-pin LQFP, supports External Bus Interface (8 CS, 25-bit address) | Required for designs needing external NOR Flash or SRAM expansion beyond on-chip memory | Select when memory footprint exceeds 128 KB or external memory mapping is mandatory |
| STM32F303VCT6 | Arm Cortex-M4F core, 256 KB Flash, 48 KB SRAM, 12-bit ADC with hardware oversampling, no LIN support | Preferred where floating-point math or higher ADC SNR is critical, but LIN networking is not required | Choose for sensor fusion or precision analog processing; avoid if LIN 2.1 compliance is mandatory |
Compared with CY9AF112LAPMC-GNE2, the CY9AF114LAPMC-GNE2 adds memory headroom and external bus capability for scalable designs, while the STM32F303VCT6 trades LIN for enhanced analog performance and FPU-making it suitable for non-automotive sensor-centric applications.

FAQ
Does CY9AF112LAPMC-GNE2 support hardware flow control on its UART channels?
No. Hardware flow control (CTS/RTS) is explicitly excluded for CY9AF112LA-series devices per the datasheet revision *H, page 2. Only channels 4–7 support FIFO buffering, but none implement automatic RTS/CTS handshaking-software-controlled flow management must be implemented externally or in firmware.
What is the maximum operating temperature range for CY9AF112LAPMC-GNE2?
The device is rated for industrial temperature range: –40 °C to +85 °C ambient, as confirmed in Section 12.2 "Recommended Operating Conditions" of datasheet 002-04672 Rev. *H. This applies to all package variants including the 80-pin LQG080 used in this part number.
Can the built-in CRC accelerator compute custom polynomials beyond CCITT CRC16 and IEEE-802.3 CRC32?
No. The hardware CRC accelerator is fixed to two generator polynomials only: 0x1021 for CCITT CRC16 and 0x04C11DB7 for IEEE-802.3 CRC32. There is no register-level configuration to load arbitrary polynomials-the block is dedicated and non-programmable per the FM3 Peripheral Manual.
Is the External Bus Interface enabled on CY9AF112LAPMC-GNE2?
No. According to the Product Lineup table (page 5), CY9AF112LA variants-including this part-do not support the External Bus Interface. The feature is present only in CY9AF112L (100-pin) and CY9AF114LA/L variants, which offer up to 8 chip selects and 25-bit addressing.
