Product details
Overview
CY9AF144MAPMC-G-MNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 256 KB dual-bank Flash, 32 KB SRAM (16 KB SRAM0 + 16 KB SRAM1), and operation up to 40 MHz. It integrates UART/CSIO/I²C serial interfaces, 24-channel 12-bit ADC (2.0 µs conversion), RTC, HDMI-CEC, and six low-power modes - deployed in industrial motor control and smart appliance main control units.
For engineers reviewing the CY9AF144MAPMC-G-MNE2 datasheet, CY9AF144MAPMC-G-MNE2 pinout, CY9AF144MAPMC-G-MNE2 application, or CY9AF144MAPMC-G-MNE2 equivalent, key selection criteria include dual-bank Flash for safe firmware updates, 5 V-tolerant GPIO support on selected pins, hardware flow control exclusion (per datasheet Rev. *D), and absence of External Bus Interface - critical for embedded BOM validation and real-time OS integration.
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 features independent I-code/D-code buses for SRAM0 and system bus for SRAM1, enabling concurrent instruction fetch and data access.
The peripheral set includes an 8-channel DMA controller with 32-bit addressing, dual watchdog timers (hardware clocked by 100 kHz CR oscillator), and CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32 - all operating within 1.65 V–3.6 V supply range and validated across Sleep, RTC, Stop, and Deep Standby power modes.
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 |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports concurrent erase/write/read per bank for robust OTA updates |
| SRAM | 32 KB total (16 KB SRAM0 on I/D bus + 16 KB SRAM1 on system bus) - isolates code/data paths to reduce bus contention |
| ADC | 24-channel 12-bit SAR, 2.0 µs conversion @ 2.7–3.6 V - meets fast-sampling requirements in motor current sensing |
| Serial Interfaces | Up to 8 channels: 4 with 16×9-bit FIFO (ch.4–7), 4 without FIFO (ch.0–3); UART/CSIO/I²C configurable per channel - flexible peripheral multiplexing |
| Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention option - extends battery life in always-on sensor hubs |
| Clock Sources | Five sources: 4–48 MHz main oscillator, 32.768 kHz sub-clock, 4 MHz/100 kHz CR oscillators, Main PLL - enables precise timing and low-power clock gating |
Pinout & Package
Package: 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual VCC/VSS pairs ensure stable core/peripheral rail decoupling; 1.65–3.6 V operation |
| P00–P07, P10–P17, etc. | General-purpose I/O | Up to 83 GPIOs; port relocate function allows dynamic peripheral pin assignment; some pins 5 V tolerant |

Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables background firmware update: one bank executes while the other is erased/written - zero-downtime field upgrades |
| Independent SRAM banks | SRAM0 (I/D bus) hosts code and stack; SRAM1 (system bus) buffers sensor data - eliminates CPU stall on DMA transfers |
| HDMI-CEC transceiver | Hardware-accelerated CEC frame generation (START/EOM/ACK) and automatic ACK reply - reduces CPU load in AV remote control stacks |
| CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 calculation from CPU - cuts integrity check latency in communication protocols |
| Two-stage LVD | LVD1 triggers interrupt for graceful shutdown; LVD2 asserts reset below threshold - prevents data corruption during brown-out |

FAQ
Does CY9AF144MAPMC-G-MNE2 support hardware flow control on UART?
No. Per the official datasheet Rev. *D, CY9AF144MAPMC-G-MNE2 - along with CY9AF141LB and CY9AF142LB - does not support hardware flow control (CTS/RTS). Only UART channel 4 on earlier FM3 variants includes this feature. Designers must implement software handshaking or external logic if flow control is required.
What is the maximum ADC sampling rate achievable with this MCU?
The 12-bit SAR ADC achieves a minimum conversion time of 2.0 µs at 2.7–3.6 V, enabling up to 500 kSPS per channel. With scanning mode and FIFO buffering (16-step depth), sustained multi-channel acquisition at ≥200 kSPS is feasible - verified under recommended operating conditions in Section 12.5 of the datasheet.
Is External Bus Interface available on CY9AF144MAPMC-G-MNE2?
No. The datasheet explicitly states that CY9AF144LB (the base variant of this part) does not support External Bus Interface. This applies to CY9AF144MAPMC-G-MNE2. Designers requiring external memory expansion must use alternative FM3 variants like CY9AF146MB or select a different MCU family with EBI support.
How is the unique device ID used in secure boot implementations?
The 41-bit factory-programmed unique ID is accessible via dedicated register and used as entropy source or hardware root-of-trust anchor. It enables cryptographic binding of firmware images to specific devices during secure boot verification - supported by Infineon's FM3 security libraries and validated in application notes AN91441 and AN92204.
