Product details
Overview
CY9AF116NAPMC-GE1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 512 KB on-chip Flash, 32 KB SRAM (split into two 16 KB banks), 100-pin LQFP package, and integrated motor control peripherals including 8-channel Base Timers, 16-channel 12-bit ADC, and QPRC for encoder position sensing - deployed in industrial motor drives and HVAC blower control systems.
For engineers reviewing the CY9AF116NAPMC-GE1 datasheet, CY9AF116NAPMC-GE1 pinout, CY9AF116NAPMC-GE1 application, or CY9AF116NAPMC-GE1 equivalent, key selection criteria include external bus interface support (25-bit address, 8-/16-bit data, 8 chip selects), LIN 2.1 compliance, hardware flow control availability on UART ch.4, dual watchdog (HW + SW), and 5V-tolerant I/O capability on selected pins.
Technical Context
This MCU implements a deterministic real-time control architecture optimized for embedded motor management: the Arm Cortex-M3 r2p1 core runs at up to 40 MHz with zero-wait-state Flash execution and supports nested interrupts across 48 peripheral sources. Its memory subsystem separates instruction and data paths via dual SRAM banks (SRAM0 on I/D-bus, SRAM1 on system bus) to reduce bus contention during DMA transfers.
The peripheral set is purpose-built for motion control: three independent 12-bit ADC units (16 total channels, 1.0 µs conversion @5 V) feed into priority/scanning modes with FIFO buffering; quadrature position/revolution counters (QPRC) accept AIN/BIN/ZIN inputs with configurable edge detection; and base timers provide PWM, PPG, reload, and PWC modes with dead-time insertion support for gate driver coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time task scheduling with low-latency interrupt response. |
| Flash Memory | 512 KB, zero-wait-state read - supports fast code execution without cache penalties in safety-critical loops. |
| SRAM | 32 KB total (SRAM0: 16 KB on I/D-bus; SRAM1: 16 KB on system bus) - isolates CPU instruction fetch from DMA-accessed data buffers. |
| ADC | 16-channel 12-bit SAR, 1.0 µs conversion @5 V - captures current/voltage feedback signals within single PWM cycle for field-oriented control. |
| Timers | 8-channel Base Timer + 2-unit Multi-function Timer + 2-unit QPRC - provides synchronized PWM generation, input capture for encoder edges, and waveform synthesis for motor commutation. |
| Communication | 8-channel multi-function serial interface (UART/CSIO/LIN/I²C), LIN 2.1 compliant, hardware flow control on ch.4 - enables robust diagnostics and actuator coordination in automotive HVAC and industrial networks. |
| Power Supply | 2.7 V to 5.5 V operation - accommodates wide-input DC-DC stages in battery-powered or 5 V rail-based motor control boards. |
Pinout & Package
Package: 100-pin LQFP (LQI100, 0.65 mm pitch), RoHS-compliant, surface-mountable with exposed thermal pad (per Infineon package drawing LBC-001).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00/TRSTX/MCSX7_1 | JTAG Debug / Memory Control | Active-low JTAG reset input; also serves as memory chip select 7 when relocated - enables boundary-scan test and external memory expansion. |
| P0A/SIN4_0/INT00_2/FRCK1_0/MCSX1_1 | Serial Input / Interrupt / Clock / Chip Select | Primary UART4 receive pin; configurable as external interrupt source or frame clock input; supports memory mapping via MCSX1 - allows flexible peripheral assignment using port relocate function. |
| P60/SIN5_0/TIOA2_2/INT15_1/MRDY_1 | Serial Input / Timer Output / Interrupt / Memory Ready | UART5 receive; timer channel A output; high-priority interrupt source; external memory ready signal - critical for synchronous data acquisition from external sensors or memory-mapped peripherals. |
| VCC (pins 1, 97, 98) | Core & I/O Power Supply | Three dedicated 2.7–5.5 V supply pins - reduces voltage drop under high-current switching of multiple I/O banks and analog circuits. |
| VSS (pins 2, 99, 100) | Ground Reference | Three isolated ground pins - separates digital, analog, and power ground domains to minimize noise coupling into ADC and timer reference paths. |
Key Features
| Feature | Design Value |
|---|---|
| Dual Watchdog Architecture | Independent hardware (CR oscillator-clocked) and software watchdogs - ensures fail-safe reset during deep sleep or clock failure, meeting IEC 61508 SIL-2 requirements. |
| External Bus Interface | 25-bit address, 8-/16-bit data, 8 chip selects - enables direct connection to external NOR Flash or SRAM for firmware updates or parameter storage beyond on-chip limits. |
| CRC Accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 calculation - offloads integrity checking from CPU during bootloader validation or CAN/LIN message reception. |
| Port Relocate Function | EPFR-controlled pin multiplexing - allows dynamic remapping of UART, timer, or ADC functions to alternate pins without PCB redesign, improving layout flexibility. |
| 5V-Tolerant I/O | Selected pins (e.g., P0F, P0E, P0D) tolerate 5 V logic levels - simplifies interface with legacy 5 V sensors, transceivers, or level-shifting circuitry. |

FAQ
What debug interfaces does CY9AF116NAPMC-GE1 support?
The device supports Serial Wire JTAG Debug Port (SWJ-DP) only - Embedded Trace Macrocell (ETM) is not implemented per datasheet Rev. *H. Debug access uses standard ARM CoreSight protocol over SWD or JTAG pins (TCK, TMS, TDI, TDO, TRSTX), enabling full breakpoint, register, and memory inspection during development and field diagnostics.
Does CY9AF116NAPMC-GE1 support hardware flow control on all UART channels?
No - hardware flow control (CTS/RTS) is supported only on UART channel 4, as explicitly stated in the datasheet. Channels 0–3 lack RTS/CTS logic; channels 5–7 are not configured for UART mode in this variant. This limitation is fixed in silicon and cannot be enabled via firmware.
What is the maximum operating frequency of the main PLL?
The main PLL supports output frequencies up to 40 MHz, derived from internal or external clock sources. It does not operate beyond 40 MHz - the Cortex-M3 core, memories, and peripherals are characterized and guaranteed only up to this frequency, with zero-wait-state Flash access maintained throughout.
Is the external bus interface available on all package variants of CY9AF116NA?
Yes - unlike earlier CY9AF111/112/114 variants, all CY9AF116NA derivatives (including CY9AF116NAPMC-GE1 in LQI100) fully support the external bus interface with 25-bit addressing, 8-/16-bit data width, and up to 8 chip selects, as confirmed in the Product Lineup table on page 5 of datasheet 002-04672 Rev. *H.
