Product details

Overview

V62/12620-01XE from Texas Instruments is an ultra-low-power mixed-signal microcontroller featuring a 16-bit RISC CPU, 2 kB Flash + 256 B information memory, 128 B RAM, and integrated peripherals including a 10-bit 200-ksps ADC, Timer_A2 with two capture/compare registers, Universal Serial Interface (USI) for SPI/I²C, and brownout detection. It operates across –40°C to 125°C and targets battery-powered aerospace, defense, and medical sensor nodes requiring long-term reliability under extreme thermal stress.

For engineers reviewing the V62/12620-01XE datasheet, V62/12620-01XE pinout, V62/12620-01XE application, or V62/12620-01XE equivalent, this page delivers verified technical context, exact pin functions, low-power mode timing behavior, real-world use cases in harsh-environment telemetry, and validated alternative options for extended-temperature MCU selection.

Technical Context

The V62/12620-01XE implements the MSP430G2230-EP variant with a digitally controlled oscillator (DCO) calibrated at factory for 1/8/12/16 MHz operation, enabling sub-1 µs wake-up from LPM4 standby. Its basic clock module supports ACLK from internal VLO or external 32-kHz crystal (limited to ≤105°C), while MCLK and SMCLK derive from DCO.

It integrates four GPIO pins on Port P1 (P1.2, P1.5, P1.6, P1.7), each supporting digital I/O, analog input (A2/A5/A6/A7), Timer_A capture/compare, USI data/clock, and interrupt with edge-selectable triggering - all configurable via dedicated SFRs including P1DIR, P1OUT, P1REN, and P1IES.

FAQ

What is the maximum operating frequency of V62/12620-01XE at 3.3 V?

V62/12620-01XE supports a maximum MCLK frequency of 16 MHz when VCC ≥ 3.3 V and duty cycle is 50% ± 10%. This is achieved using the factory-calibrated DCO setting stored in Flash segment A (CALBC1_16MHZ/CALDCO_16MHZ). The CPU executes instructions directly from MCLK, so instruction throughput scales linearly with this clock rate.

Does V62/12620-01XE support external crystal oscillators?

V62/12620-01XE supports a 32-kHz crystal on XIN/XOUT pins for ACLK generation, but TI documentation explicitly states that crystal oscillator operation is limited to ≤105°C. Since V62/12620-01XE is rated for –40°C to 125°C operation, use of the crystal is restricted to applications where junction temperature remains below 105°C; otherwise, the internal VLO oscillator must be selected for ACLK.

How many analog input channels does the ADC10 module in V62/12620-01XE support?

The ADC10 module in V62/12620-01XE supports four analog input channels: A2, A5, A6, and A7 - each mapped to dedicated pins P1.2, P1.5, P1.6, and P1.7 respectively. These channels are accessible via the ADC10CTL1 register's INCHx bits and support autoscan mode for sequential conversion without CPU intervention.

Can V62/12620-01XE perform in-system programming without external hardware?

Yes, V62/12620-01XE supports in-system programming via its integrated Spy-Bi-Wire interface using only two pins (RST/NMI/SBWTDIO and TEST/SBWTCK). No external programming voltage is required - the device draws programming power from DVCC, and firmware updates can be executed in the field using standard TI Flash programming tools and protocols.

What is the purpose of the security fuse in V62/12620-01XE?

The security fuse in V62/12620-01XE, when blown, permanently disables read access to Flash memory and prevents unauthorized firmware extraction or reverse engineering. It is programmed via the TEST pin during final test and cannot be reset - ensuring code integrity and intellectual property protection in defense and medical applications where tamper resistance is mandated.
