It features 32KB of non-volatile FRAM (Ferroelectric Random Access Memory) for program storage and 4KB of SRAM for data processing. The integrated Smart Analog Combo (SAC) modules provide configurable operational amplifiers, programmable gain amplifiers, DACs, and comparators, making this device ideal for precision sensing and measurement applications. FRAM technology combines the speed of SRAM with the non-volatility of Flash, enabling flexible memory partitioning and instant write capabilities with virtually unlimited endurance.","working_principle":"The MSP430FR2155TDBTR operates on a 16-bit RISC architecture capable of up to 24 MHz operation. The CPU executes instructions from FRAM with single-cycle access. Four Smart Analog Combo (SAC-L3) modules each contain a programmable gain amplifier (PGA), a 12-bit DAC, and a comparator that can be independently configured. The 12-bit ADC with 10 channels and 200 ksps sampling rate converts analog sensor signals to digital values. The device supports multiple low-power modes including LPM3 (1.43 \u00b5A with RTC active) and LPM4.5 (42 nA) to extend battery life in portable applications. Communication peripherals include eUSCI modules supporting UART, SPI, and I2C protocols.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>P1.1\/UCB0CLK\/ACLK\/OA0O\/COMP0.1\/A1<\/td><td>Port 1.1 \/ I2C CLK \/ ACLK \/ Op-Amp0 Output \/ Comparator0.1 \/ ADC A1<\/td><\/tr><tr><td>2<\/td><td>P1.0\/UCB0STE\/SMCLK\/COMP0.0\/A0\/Veref+<\/td><td>Port 1.0 \/ SPI STE \/ SMCLK \/ Comparator0.0 \/ ADC A0 \/ Ext Ref+<\/td><\/tr><tr><td>3<\/td><td>TEST\/SBWTCK<\/td><td>Test pin \/ Spy-Bi-Wire Test Clock<\/td><\/tr><tr><td>4<\/td><td>RST\/NMI\/SBWTDIO<\/td><td>Reset \/ NMI \/ Spy-Bi-Wire Data I\/O<\/td><\/tr><tr><td>5<\/td><td>DVCC<\/td><td>Digital Supply Voltage<\/td><\/tr><tr><td>6<\/td><td>DVSS<\/td><td>Digital Ground<\/td><\/tr><tr><td>7<\/td><td>P2.7\/TB0CLK\/XIN<\/td><td>Port 2.7 \/ Timer_B0 Clock \/ Crystal Input<\/td><\/tr><tr><td>8<\/td><td>P2.6\/MCLK\/XOUT<\/td><td>Port 2.6 \/ MCLK \/ Crystal Output<\/td><\/tr><tr><td>17<\/td><td>P1.7\/UCA0TXD\/UCA0SIMO\/TB0.2\/TDO\/OA1+\/A7\/VREF<\/td><td>Port 1.7 \/ UART TX \/ SPI MOSI \/ Timer_B0.2 \/ TDO \/ Op-Amp1+ \/ ADC A7<\/td><\/tr><tr><td>18<\/td><td>P1.6\/UCA0RXD\/UCA0SOMI\/TB0.1\/TDI\/TCLK\/OA1-\/A6<\/td><td>Port 1.6 \/ UART RX \/ SPI MISO \/ Timer_B0.1 \/ TDI \/ Op-Amp1- \/ ADC A6<\/td><\/tr><\/table>","application_scenarios":"The MSP430FR2155TDBTR is widely used in battery-powered sensing applications such as smoke detectors where its ultra-low power consumption and integrated analog peripherals reduce BOM count. In industrial sensor transmitters, the SAC modules enable direct signal conditioning without external op-amps. The FRAM memory provides reliable data retention during power loss events, making it suitable for circuit breakers and power meters that must maintain state information. Its low-power modes enable years of operation from coin-cell batteries in portable measurement devices.","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>MSP430FR2355TDBTR<\/td><td>Texas Instruments<\/td><td>Same family, different memory config<\/td><\/tr><tr><td>MSP430FR2153TDBTR<\/td><td>Texas Instruments<\/td><td>16KB FRAM variant<\/td><\/tr><tr><td>MSP430FR2433TDBTR<\/td><td>Texas Instruments<\/td><td>16KB FRAM, no SAC modules<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6475","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=6475"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6475\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=6475"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=6475"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=6475"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=6475"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
