Product details
Overview
CY9AF114NAPF-G-JNE1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 256 KB on-chip Flash, 32 KB SRAM (16 KB SRAM0 + 16 KB SRAM1), 100-pin LQFP package, and operating voltage range of 2.7 V to 5.5 V. It integrates dual watchdog timers (HW + SW), CRC accelerator (CCITT CRC16/IEEE-802.3 CRC32), and supports motor control via 8-channel Base Timers and 2-unit Multi-function Timers. Used in industrial motor drives requiring real-time PWM, A/D conversion, and LIN communication.
For engineers reviewing the CY9AF114NAPF-G-JNE1 datasheet, CY9AF114NAPF-G-JNE1 pinout, CY9AF114NAPF-G-JNE1 application, or CY9AF114NAPF-G-JNE1 equivalent, key selection criteria include verified 40 MHz operation, 16-channel 12-bit ADC with 1.0 μs conversion time at 5 V, external bus interface (25-bit address, 8-/16-bit data, 8 chip selects), LIN 2.1 support, and SWJ-DP debug interface without ETM.
Technical Context
The CY9AF114NAPF-G-JNE1 implements an Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer for OS task scheduling. Its memory subsystem features zero-wait-state Flash execution and dual-bus SRAM architecture-SRAM0 connected to I-code/D-code buses and SRAM1 on the system bus-enabling concurrent CPU and DMA access.
Peripherals include eight configurable Base Timers (PWM/PPG/reload/PWC modes), two QPRC units for encoder position sensing, and a full-featured multi-function serial interface with four FIFO-equipped channels (ch.4–ch.7) supporting UART, CSIO, LIN 2.1, and I²C up to 400 kbps. The hardware watchdog runs from the 100 kHz built-in CR oscillator, remaining active in SLEEP and TIMER low-power modes.

FAQ
What is the maximum operating frequency and clock source configuration for CY9AF114NAPF-G-JNE1?
The CY9AF114NAPF-G-JNE1 operates at up to 40 MHz using the main PLL clock, which can be driven by an external crystal (4–48 MHz) or the internal 4 MHz CR oscillator. Clock supervision is provided by the CSV module, which monitors external clock integrity using the 32.768 kHz sub-clock or internal CR sources and asserts reset on failure.
Does CY9AF114NAPF-G-JNE1 support hardware flow control for UART, and which channels implement it?
No, hardware flow control (CTS/RTS) is explicitly excluded from CY9AF114NAPF-G-JNE1 per datasheet Rev. *H: "CY9AF111LA, F112LA, F114LA, F112L and F114L do not support Hardware Flow control." Only UART channels 0–3 are available without FIFO; channels 4–7 support FIFO but lack RTS/CTS signaling capability.
How many A/D converter units are integrated, and what is their effective resolution and sampling rate?
The CY9AF114NAPF-G-JNE1 integrates three 12-bit successive approximation A/D converter units (totaling 16 input channels), with guaranteed 1.0 μs conversion time at 5 V supply. Resolution remains 12-bit across full operating voltage (2.7–5.5 V); no oversampling or dithering is implemented in hardware per the peripheral manual.
Is the External Bus Interface functional on CY9AF114NAPF-G-JNE1, and what memory types does it support?
Yes, the External Bus Interface is fully supported on CY9AF114NAPF-G-JNE1, enabling connection to SRAM and NOR Flash devices. It provides up to 8 chip selects, 25-bit addressing (up to 256 MB), and configurable 8-/16-bit data width with address/data multiplexing and external RDY handshake - confirmed in Product Lineup table (Page 5) and Section 1.2 of datasheet 002-04672 Rev. *H.
