Product details
Overview
MSP430FR69221IG56R from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller featuring 64KB nonvolatile FRAM, 2KB RAM, integrated 12-bit ADC with 8 external channels, 116-segment LCD driver, and dual eUSCI modules supporting UART, IrDA, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered utility meters and portable medical devices.
For engineers reviewing the MSP430FR69221IG56R datasheet, MSP430FR69221IG56R pinout, MSP430FR69221IG56R application, or MSP430FR69221IG56R equivalent, key selection criteria include LPM3.5 RTC current (0.35 µA), FRAM endurance (10¹⁵ write cycles), AES256 encryption coprocessor support, TSSOP-56 package compatibility, and I²C-based BSL functionality.
Technical Context
The MSP430FR69221IG56R implements the MSP430 CPUXV2 core with 16 registers and executes instructions at up to 16 MHz using a factory-trimmed DCO or external 32-kHz LFXT crystal. Its low-power architecture includes seven operating modes, with LPM3.5 enabling real-time clock operation at 0.35 µA typical while retaining full FRAM and register state.
Peripherals are tightly integrated: three 16-bit timers (TA0–TA3, TB0) provide capture/compare and PWM; the 12-bit ADC12_B supports internal reference and sample-and-hold; and the LCD_C module drives up to 116 segments in static or 2–4 multiplex configurations. AES256 encryption is implemented in hardware for secure firmware updates and data protection.

FAQ
What is the primary difference between MSP430FR69221IG56R and MSP430FR6922IG56?
The MSP430FR69221IG56R features an I²C-based bootloader (BSL) using P1.6/BSL_DAT and P1.7/BSL_CLK, whereas the MSP430FR6922IG56 uses a UART-based BSL on P2.0/BSL_TX and P2.1/BSL_RX. This makes MSP430FR69221IG56R compatible with I²C-only programming infrastructure and eliminates UART transceiver requirements in production test fixtures.
Does MSP430FR69221IG56R support high-frequency crystal (HFXT) operation?
No. The MSP430FR69221IG56R does not implement HFXIN or HFXOUT pins - confirmed by functional block diagram notes and device comparison tables. It supports only DCO and LFXT (32 kHz) clock sources, making it optimized for ultra-low-power RTC and sensor applications where HFXT is unnecessary.
What LCD configuration does MSP430FR69221IG56R support?
The MSP430FR69221IG56R integrates the LCD_C peripheral supporting up to 116 segments in static mode or 2–4 multiplex configurations. Segment assignments vary by package; for the TSSOP-56 (DGG), up to 100 segments are supported - verified in Table 3-1 and Figure 4-3 pin diagrams.
Is AES256 encryption available on MSP430FR69221IG56R?
Yes. AES256 hardware acceleration is implemented on MSP430FR69221IG56R, as confirmed in Section 1.1 Features and functional block diagram. It supports both encryption and decryption operations and is accessible via the standard MSP430FR69xx AES peripheral register map - distinct from MSP430FR682x/FR687x variants which lack this feature.
What is the maximum operating frequency of MSP430FR69221IG56R?
The MSP430FR69221IG56R operates at up to 16 MHz using its factory-trimmed DCO oscillator. This maximum frequency is maintained across the full 1.8 V–3.6 V supply range and is validated in the Recommended Operating Conditions table (Section 5.3) of the official datasheet SLASE23E.
