Product details
Overview
MSP430F5510CY from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with integrated full-speed USB 2.0 PHY, 32 KB flash, 4 KB + 2 KB RAM, 10-bit ADC (8 channels: 6 external, 2 internal), two USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers, RTC, and hardware multiplier - designed for battery-powered sensor systems and USB-connected data loggers.
For engineers reviewing the MSP430F5510CY datasheet, MSP430F5510CY pinout, MSP430F5510CY application, or MSP430F5510CY equivalent, key selection criteria include USB 2.0 host/device capability, sub-2 µA LPM3 current at 3 V, 5 µs wake-up time, 47 GPIOs in 64-pin RGC package, and dual USCI support for simultaneous UART + I²C or dual SPI interfaces.
Technical Context
The MSP430F5510CY implements a unified clock system with FLL stabilization, programmable LDO core regulation, and flexible port mapping via P4 controller - enabling dynamic reconfiguration of USCI functions on shared pins. Its USB subsystem integrates PHY, 3.3-V/1.8-V power system, and USB-PLL, supporting eight endpoints without external transceivers.
It features three-channel DMA, EEM (Enhanced Emulation Module), and segmented memory architecture optimized for low-power real-time execution. The device supports up to 25 MHz system clock, with DCO-based active-mode operation and multiple low-power modes (LPM0–LPM4.5) preserving full RAM retention down to 0.18 µA in shutdown.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5529IPN | Same 64-pin LQFP package, identical peripheral set, but 64 KB flash and 8 KB RAM - no USB SRAM differentiation. | Higher memory capacity suits firmware with complex USB class stacks (CDC, HID, MSC) or large data buffers. | Select when >32 KB flash is required for feature-rich USB device firmware or future-proofing. |
| MSP430F6638IZQ | 80-pin nFBGA, 128 KB flash, 16 KB RAM, enhanced ADC (12-bit, 16-channel), but lacks integrated USB PHY - requires external transceiver. | Better analog front-end and larger memory for high-precision measurement systems where USB is secondary. | Choose when higher-resolution ADC or greater program storage is prioritized over USB integration simplicity. |

FAQ
What is the maximum system clock frequency supported by the MSP430F5510CY?
The MSP430F5510CY supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This frequency is fully operational across the specified voltage range (1.8 V to 3.6 V) and enables high-throughput USB transfers and real-time sensor processing without external crystal dependency.
Does the MSP430F5510CY require an external USB transceiver?
No, the MSP430F5510CY does not require an external USB transceiver. It integrates a full-speed USB 2.0 PHY, USB-PLL, and dedicated 3.3-V/1.8-V USB power system - allowing direct connection of DP/DM lines to a USB connector with only standard 27 Ω series resistors and proper PCB routing.
How many analog input channels does the MSP430F5510CY ADC support?
The MSP430F5510CY features a 10-bit ADC (ADC10_A) with 8 total input channels: 6 external analog inputs (A0–A5) and 2 internal references (VeREF+ and VeREF−). This configuration supports simultaneous monitoring of multiple sensors while retaining internal calibration sources for self-test and offset correction.
What low-power modes are available on the MSP430F5510CY, and what is the lowest current draw?
The MSP430F5510CY supports five low-power modes (LPM0–LPM4.5). The lowest current draw is in LPM4.5 (shutdown mode) at 0.18 µA at 3 V, with full RAM retention and fast wakeup. LPM3 draws 1.9 µA at 2.2 V with RTC, watchdog, and supervisor active - ideal for time-triggered sensor sampling.
Can the USCI modules on the MSP430F5510CY operate simultaneously with different protocols?
Yes, the MSP430F5510CY's two USCI modules (USCI_A0/A1 and USCI_B0/B1) can operate concurrently with different protocols - for example, USCI_A0 in UART mode for Bluetooth communication while USCI_B0 runs I²C to interface with environmental sensors - with no resource conflict due to independent hardware blocks and DMA support.
