MSP430F448IPZ - 8MHz 48KB MCU | Texas Instruments
部品番号: MSP430F448IPZ ✓ 生産中MSP430F448IPZ 概要
A mixed-signal microcontroller combines a programmable digital controller with analog measurement functions on one integrated circuit. The MSP430F448 belongs to the MSP430 family of ultra-low-power RISC microcontrollers, where the CPU core, memory, timers, serial interfaces, and analog peripherals share a low-power architecture. The 16-bit RISC instruction set and 16-bit registers support efficient control workloads, while hardware peripherals allow measurements and communications to continue without excessive software overhead.
Key features include an 8 MHz maximum clock frequency, 48 KB flash for firmware storage, 2 KB SRAM for working data, and a 12-bit ADC for analog sensing. The integrated comparator supports threshold-based signal detection, while SPI and UART provide wired peripheral connectivity. According to the manufacturer datasheet, active-mode current is 280 uA at 1 MHz and 2.2 V, standby current is 1.1 uA, and RAM-retention off-mode current is 0.1 uA. Wake-up from standby takes less than 6 us.
The MSP430 architecture is based on a 16-bit RISC core with 16-bit registers and constant generators. Five power-saving modes let firmware balance response time against energy use, which is particularly valuable in battery-operated measurement equipment. The 12-bit ADC and comparator place analog input conditioning and digital control in the same device, while the LCD controller can drive up to 160 segments without requiring a separate display controller. The integrated communication peripherals reduce board area in compact instruments.
Typical applications include low-power industrial measurement systems, portable environmental monitors, digital multimeters, data loggers, smart metering equipment, battery-powered instrumentation, and control panels with segment LCD displays. The device is particularly suitable when a compact 100-pin package can accommodate the extensive analog and LCD resources without requiring a separate LCD driver or precision converter.
Design around the MSP430F448IPZ requires attention to decoupling, analog grounding, LCD drive routing, and low-power behavior. Place input and output capacitors close to their associated power pins, keep analog traces away from fast-switching LCD and serial signals, and use the manufacturer pin-description table when assigning all 100 pins. Firmware should configure unused peripherals and GPIO pins appropriately to avoid unintended current consumption.
This page combines manufacturer specifications, procurement information, drop-in replacement research, and application-focused engineering guidance. It also identifies differences among nearby MSP430 devices so that designers can verify memory capacity, peripheral availability, pin compatibility, and operating requirements before approving a substitution.

主な用途
MSP430F448IPZ の用途: 6 件s: Low-Power Digital Multimeter, Portable Environmental Monitor, Industrial Process Monitor, Battery-Powered Data Logger, Segment LCD Control Panel, Smart Metering Equipment.
Low-Power Digital Multimeter
The MSP430F448IPZ suits a handheld digital multimeter because its 12-bit ADC measures analog inputs while the 16-bit RISC core performs range selection, calculation, display updates, and keypad handling. The integrated comparator can support threshold or overvoltage detection, and the 160-segment LCD controller can drive a segmented instrument display. At 1 MHz and 2.2 V, active current is 280 uA, while standby current falls to 1.1 uA, supporting long intervals between measurements. Firmware should disable unused converters and peripheral clocks between readings to minimize battery drain.
おすすめ
Portable Environmental Monitor
A battery-powered environmental monitor benefits from the MSP430F448IPZ combination of a 12-bit ADC, comparator, 48 KB flash, and low-power modes. Sensor analog signals can be sampled by the ADC, while the comparator can detect threshold crossings without continuous software polling. The microcontroller's 280 uA active current at 1 MHz and 2.2 V complements low-leakage sensors, and the 1.1 uA standby specification supports duty-cycled operation. Use the 2 KB SRAM for short measurement batches and configure unused GPIO and analog blocks to avoid leakage.
おすすめ
Industrial Process Monitor
The MSP430F448IPZ can serve as the control and communications hub in a compact industrial process monitor. Its 12-bit ADC handles standard analog process inputs, the comparator provides fast threshold detection, and SPI or UART connects to a sensor, local display, or remote controller. The 48 KB flash accommodates protocol handling and local configuration, while the 160-segment LCD controller supports a local panel. Its -40 C to +85 C rating suits industrial equipment, although the final design must protect analog inputs from transients and maintain clean supply decoupling.
おすすめ
Battery-Powered Data Logger
For periodic field measurements, the MSP430F448IPZ combines low standby consumption with enough flash and SRAM for local buffering. The 48 KB program memory supports firmware, configuration, and compact event records, while the 2 KB SRAM can hold short acquisition batches. Its ADC can sample transducers, and the comparator can signal threshold events. With 0.1 uA specified off current when RAM is retained and less than 6 us standby wake-up time, the device is suited to duty-cycled logging where interval energy and sensor standby current dominate the battery budget.
おすすめ
Segment LCD Control Panel
The MSP430F448IPZ is effective in segment-display products because its LCD controller supports 160 segments and the CPU can manage menu logic, button input, and status indicators in one device. Integrated SPI and UART interfaces allow connection to remote equipment or configuration tools. Operating from 1.8 V to 3.6 V supports low-voltage embedded systems, and the five power-saving modes help control energy use when the panel is idle. PCB layout should isolate LCD drive routing from sensitive analog inputs and verify segment drive current against the manufacturer's electrical limits.
おすすめ
Smart Metering Equipment
The MSP430F448IPZ is well suited to smart metering front ends that need low standby power, local display control, and serial communications. The 12-bit ADC can acquire current or voltage-related signals, while the comparator can perform fast threshold supervision. SPI or UART supports communication with a metering front end, and the 160-segment LCD controller can support local readouts. At 280 uA active current at 1 MHz and 2.2 V, the MCU is suitable for duty-cycled metering when the power budget also accounts for sensor excitation, display loading, and radio or communications bursts.

主な差別化要因
- 48 KB flash with integrated analog and LCD resources （vs MSP430F436IPZR)

- Low-power mixed-signal integration （vs MSP430F447IPZ)
設計ノート
Route sensitive analog inputs away from LCD drive, SPI clock, UART activity, and switching power-supply nodes. Place the MCU decoupling capacitors directly beside the appropriate VDD and AVSS pins, with the shortest possible return path. Keep the 12-bit ADC input network away from high-current LCD outputs because their switching edges can couple into the measurement result even when the MCU is operating at 8 MHz.
Budget the MSP430F448IPZ across active, standby, and off states rather than using only the 280 uA active-mode figure at 1 MHz and 2.2 V. The device also specifies 1.1 uA in standby and 0.1 uA off with RAM retention. External sensors, LCD bias circuitry, pull resistors, and communication transceivers can dominate the system current, so disable unused blocks and measure the complete assembled board in each operating state.
Use the manufacturer pin-description table for every assignment in the 100-pin PZ package, including alternate peripheral functions and reserved pins. Preserve the recommended crystal or clock-circuit layout and avoid long traces beneath the MCU. Because the LCD and analog functions share a large pin-rich package, a PCB review should check LCD segment drive current, analog input impedance, and exposed route clearance against the device electrical characteristics.
Do not approve an MSP430x4xx substitute solely because it uses the same 100-pin LQFP footprint. Compare flash and SRAM requirements, ADC and comparator availability, LCD segment capacity, UART and SPI channel count, clock limits, supply range, and temperature grade. Changes in alternate pin functions can alter the PCB schematic even when the mechanical package and board outline remain identical.
