Product details

Overview

CY9AF116NAPMC-G-MNE2 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, 3-unit 12-bit ADC (16 channels), QPRC, LIN 2.1 support, and hardware CRC accelerator - deployed in industrial motor drives and HVAC control systems.

For engineers reviewing the CY9AF116NAPMC-G-MNE2 datasheet, CY9AF116NAPMC-G-MNE2 pinout, CY9AF116NAPMC-G-MNE2 application, or CY9AF116NAPMC-G-MNE2 equivalent, key selection criteria include 40 MHz max CPU frequency, 2.7–5.5 V supply range, dual watchdog (HW + SW), external bus interface (25-bit address, 8/16-bit data, 8 chip selects), and 83 GPIOs with port relocation and 5V-tolerant I/O capability.

Technical Context

This MCU implements a deterministic real-time control architecture centered on the Arm Cortex-M3 r2p1 core, with tightly coupled memory buses (I-code/D-code for SRAM0, system bus for SRAM1) enabling zero-wait-state Flash execution at 40 MHz. Its peripheral subsystem integrates time-critical functions: dual QPRC units for encoder position tracking, DTIF-triggered emergency stop logic, and A/D activation compare for synchronized sampling.

The clock system combines five sources (main oscillator, sub-clock, two CR oscillators, PLL) with Clock Supervisor (CSV) monitoring external clock integrity and Low-Voltage Detector (LVD) providing two-stage reset/interrupt thresholds. Debug uses Serial Wire JTAG (SWJ-DP); ETM is not supported per datasheet Rev. *H.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 32-bit motor control microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F303VCT6	ARM Cortex-M4F core, 256 KB Flash, 48 KB SRAM, no external bus interface, integrated op-amps/comparators	Better analog signal conditioning but lacks QPRC and LIN; requires external transceiver for LIN networks	Select when analog front-end integration outweighs encoder interface depth and LIN protocol stack offload.
RA4M1 (R7FA4M1AB3CFM)	ARM Cortex-M4, 256 KB Flash, 32 KB SRAM, no external bus, 12-bit ADC (24 ch), no QPRC, SCI with LIN mode	Lacks dedicated QPRC and DTIF; LIN implemented in software/firmware layer rather than hardware peripheral	Prefer for cost-sensitive consumer appliances where encoder resolution ≤ 10-bit and emergency stop latency > 10 μs is acceptable.

Compared with STM32F303VCT6 and RA4M1, CY9AF116NAPMC-G-MNE2 delivers superior deterministic motor control via hardware QPRC, DTIF, and LIN 2.1 compliance - reducing firmware complexity and worst-case interrupt latency by 3.2 μs in safety-critical drive applications.

FAQ

What debug interface does CY9AF116NAPMC-G-MNE2 support?

CY9AF116NAPMC-G-MNE2 supports Serial Wire JTAG Debug Port (SWJ-DP) only - Embedded Trace Macrocell (ETM) is explicitly excluded per datasheet Rev. *H. SWJ-DP provides full programming, breakpoint, and real-time variable watch capabilities using standard ARM CoreSight tools and Infineon's ModusToolbox IDE.

Does this MCU support 5V-tolerant I/O pins?

Yes - CY9AF116NAPMC-G-MNE2 includes 5V-tolerant GPIOs (specifically on CY9AF115MA/NA and CY9AF116MA/NA variants per datasheet Page 3). Pin compatibility is confirmed in the "Pin Description" section; tolerance applies only when VCC ≥ 4.5 V and input voltage ≤ 5.5 V.

Is the External Bus Interface available on this part?

Yes - CY9AF116NAPMC-G-MNE2 supports the full External Bus Interface: 25-bit address bus, 8-/16-bit data bus, up to 8 chip selects, SRAM/NOR Flash compatibility, and external RDY handshake - unlike CY9AF111LA/F112LA/F114LA which omit this feature entirely.

What LIN protocol version is implemented in hardware?

CY9AF116NAPMC-G-MNE2 implements LIN protocol Revision 2.1 in dedicated hardware within its multi-function serial interface (ch.0–ch.3). It supports master/slave modes, configurable break field (13–16 bit), break delimiter (1–4 bit), and automatic checksum calculation - eliminating software overhead for LIN frame assembly and validation.
