FRAM-based 16-bit MCU for industrial and metering applications
Its program memory is 64 KB of FRAM — a non-volatile memory that writes at near-SRAM speed with essentially unlimited endurance, unlike Flash. This makes it a strong fit for applications that log data frequently, update firmware over the air, or need low-power operation with fast wake-up. The device integrates 46 general-purpose I/O, an 8-channel 12-bit ADC, and serial interfaces including I²C, SPI, and UART.
64 KB FRAM — what it means for firmware and data logging
FRAM writes at bus speed with no erase-before-write penalty, so the 64 KB program space doubles as a data-logging buffer without wearing out. The 2 KB of RAM handles stack and scratchpad variables. For designs that need to store calibration constants or event logs in the same memory as the firmware, FRAM eliminates the separate EEPROM or battery-backed SRAM.
16 MHz CPU and peripheral set for real-time control
The 16 MHz CPUXV2 core delivers about 16 MIPS, enough for closed-loop control loops at tens of kilohertz. The built-in peripherals include a brown-out reset, DMA controller, LCD driver, POR, PWM, and watchdog timer. The 8-channel 12-bit ADC samples at sufficient rate for multi-sensor acquisition in industrial transmitters or energy-monitoring sub-systems.
Package and footprint — 56-TSSOP
Housed in a 56-pin TSSOP (6.10 mm body width), the part is a surface-mount device suited for automated assembly. The 0.65 mm pitch is standard for this pin count; the package is compatible with reflow soldering at MSL 3 (verify floor life per the reel label).
TI lists the MSP430FR6822IG56R as Active.
