Product details
Overview
CY9AF112MAPMC-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 CPU frequency, and integrated motor control peripherals including 8-channel Base Timers, 2-unit Multi-function Timers, 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 CY9AF112MAPMC-GNE2 datasheet, CY9AF112MAPMC-GNE2 pinout, CY9AF112MAPMC-GNE2 application, or CY9AF112MAPMC-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 version, hardware flow control exclusion in UART ch.4–ch.7, and dual watchdog (HW + SW) with CSV and LVD supervision.
Technical Context
This MCU implements the Arm Cortex-M3 r2p1 core with nested vectored interrupt controller supporting 48 peripheral interrupts and 16 priority levels. It integrates three independent 12-bit successive-approximation ADC units (total 12 channels), each with 1.0 μs conversion time at 5 V and configurable FIFO depth for scan/priority modes.
The peripheral set includes an 8-channel DMA controller with independent bus access, quadrature position/revolution counters (2 units), and multi-function serial interfaces-four with 16×9-bit FIFO (ch.4–ch.7) and four without FIFO (ch.0–ch.3)-supporting UART, CSIO, LIN 2.1, and I²C (up to 400 kbps).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max operation - enables deterministic real-time control with low-latency interrupt handling. |
| Flash Memory | 128 KB, 0 wait-state read - supports fast code execution without pipeline stalls in timing-critical loops. |
| SRAM | 16 KB total (SRAM0 + SRAM1), split across I-code/D-code and system buses - allows concurrent instruction fetch and data access. |
| ADC | 12-bit, 12 channels, 1.0 μs conversion @5 V - delivers high-resolution analog sensing for motor current/voltage feedback. |
| Timers | 8-channel Base Timer (PWM/PPG/reload), 2-unit MF-Timer (6 output compare, 4 input capture per unit) - enables precise waveform generation and encoder signal decoding. |
| Serial Interfaces | 8-channel multi-function UART/CSIO/LIN/I²C - provides flexible communication for sensor networks, actuator control, and diagnostics. |
| Power Supply | 2.7 V to 5.5 V operating range - ensures compatibility with industrial 3.3 V and 5 V logic domains and brown-out resilience. |
Pinout & Package
Package: 80-pin LQFP (LQG064, 0.65 mm pitch), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pins 1, 22, 44, 66, 80) | Core & I/O power supply | Five dedicated 2.7–5.5 V supply pins ensure stable voltage distribution and reduce IR drop across high-current peripheral operation. |
| VSS (Pins 2, 21, 43, 65, 79) | Digital ground reference | Five ground pins provide low-impedance return paths for mixed-signal operation and EMI suppression. |
| P0A–P09, P20, P50–P51, etc. | Multi-function GPIO / peripheral I/O | 66 programmable pins support port relocation via EPFR register - enables flexible PCB layout and function remapping without hardware change. |
| TCK/SWCLK, TMS/SWDIO, TDO/SWO, TRSTX | SWJ-DP debug interface | Four-pin Serial Wire JTAG Debug Port enables non-intrusive firmware debugging, flash programming, and real-time trace without dedicated debug header. |
| INT00_0–INT15_0, NMI | External interrupt inputs | 11 configurable external interrupt pins plus one NMI - supports fast response to safety-critical events like overcurrent or emergency stop. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware Watchdog + Software Watchdog | Dual independent watchdogs - HW watchdog runs on 100 kHz CR oscillator, remaining active in SLEEP/TIMER modes for fail-safe recovery. |
| Clock Supervisor (CSV) | Detects external clock failure or frequency anomaly - triggers interrupt or reset to prevent timing-related system lockup. |
| CRC Accelerator (CRC16/32) | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation - reduces CPU load during firmware update validation and communication frame integrity checks. |
| Low-Voltage Detector (LVD1/LVD2) | Two-stage voltage monitoring - LVD1 asserts interrupt for early warning; LVD2 forces auto-reset below critical threshold to prevent corrupted memory writes. |
| Port Relocate Function | EPFR-based peripheral pin assignment - eliminates fixed pin conflicts and enables optimal routing of high-speed signals like PWM or encoder inputs. |
Applications
| Industrial Motor Drive | Automotive Body Control Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit Arm Cortex-M3 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103C8T6 | 64 KB Flash, 20 KB SRAM, no LIN support, 2× 12-bit ADC (10 ch), no QPRC or CSV | Lacks native LIN 2.1 and clock supervision - requires external components for automotive diagnostics and clock fault tolerance | Select when cost is primary constraint and LIN/Clock Supervision are not required |
| RA4M1 (R7FA4M1AB3CFM) | 256 KB Flash, 32 KB SRAM, 48 MHz, 12-bit ADC (24 ch), no external bus interface, no hardware flow control | Includes TrustZone security but omits hardware flow control on UART - limits high-throughput serial bridging use cases | Select for enhanced security needs and higher memory headroom where UART flow control is managed in software |
Compared with STM32F103C8T6 and RA4M1, CY9AF112MAPMC-GNE2 uniquely combines LIN 2.1 compliance, dual watchdogs with CR-based HW watchdog, and CSV in a 80-pin LQFP - making it optimal for cost-constrained industrial motor control where protocol fidelity and clock reliability are non-negotiable.

FAQ
Does CY9AF112MAPMC-GNE2 support hardware flow control on UART channels?
No. Hardware flow control (CTS/RTS) is explicitly excluded for CY9AF112LA/MA/NA/NB variants per datasheet Rev. *H, page 2. Only UART channels 4–7 support FIFO buffering; none support automatic RTS/CTS handshaking. Flow control must be implemented in software or via external logic if required.
What is the maximum ADC sampling rate achievable with this MCU?
At 1.0 μs per conversion (per datasheet section 12.5), the 12-bit ADC achieves up to 1 MSPS per channel. With scanning mode and FIFO, sustained throughput reaches 16 samples per scan cycle. Total aggregate rate depends on channel count and priority configuration - e.g., 12 channels scanned at 100 kSPS average with interleaved priority levels.
Is external bus interface available on CY9AF112MAPMC-GNE2?
No. The CY9AF112LA/MA/NA/NB series lacks external bus interface support, as confirmed in the Product Lineup table (page 5) and feature summary (page 2). This variant supports only internal memory and peripheral interfaces - no SRAM/NOR Flash expansion via address/data bus.
Can the built-in CRC accelerator compute custom polynomials?
No. The CRC accelerator supports only two fixed generator polynomials: CCITT CRC16 (0x1021) and IEEE-802.3 CRC32 (0x04C11DB7), as specified in section "CRC Accelerator" (page 4). Custom polynomial configuration is not supported in hardware; such operations require software implementation.
