Texas Instruments unveils MSPM33C321A mixed-signal Cortex-M33 microcontroller with 256KB SRAM, 1MB flash

Texas Instruments MSPM33C321A is a new Arm Cortex-M33 mixed-signal microcontroller clocked at 160MHz, with up to 1MB of flash with ECC and 256kB SRAM with ECC, and a range of digital and analog peripherals. Those include 9.4MSPS dual SAR ADCs and comparators, QSPI, UART, SPI, I2C, I2S/TDM, & CAN-FD interfaces, and the company also highlights a separate VBAT power domain with RTC, integrated watchdog, and tamper I/O, as well as low power consumption with a 16µA standby current with 64kB SRAM and CPU/register retention. The MSPM33C321A also has a little brother with 512KB flash called the MSPM33C3219. MSPM33C321A specifications: MCU...

The first good Raspberry Pi Laptop

Ever since the Raspberry Pi Compute Module 5 was introduced, I wondered why nobody built a decent laptop chassis around it.

You could swap out a low spec CM5 for a higher spec, and get an instant computer upgrade. Or, assuming a CM6 comes out someday in the same form factor, the laptop chassis could get an entirely new life with that upgrade.

Электровакуумные геттеры. Общие положения, классификация, первые газопоглотители

Рассмотрев газопоглощение и газовыделение электровакуумных материалов [1], мы пришли к неминуемому и неутешительному выводу: без большой работы по очистке и извлечению газов из металлов, стекла, слюды и керамики в радиолампах, срок жизни готовых приборов будет весьма недолгим, а параметры неутешительными. Специальный же элемент в лампе — газопоглотитель, иначе геттер, появляющиеся нежелательные газы связывает, существенно продлевая жизнь электровакуумным приборам (ЭВП) и стабилизируя их электрические характеристики. Геттер, в сущности являясь местным миниатюрным одноразовым высоковакуумным насосом, позволяет обойтись при изготовлении массовых ламп их быстрой и сравнительно неглубокой откачкой, радикально снижая стоимость производства и цену готовых приборов. Так как же работает геттер, какие они бывают, что за геттеры...

Compact, fanless DIN-Rail Intel Core Ultra 5 235U/7 265U industrial PC targets AMR, robotics, and computer vision

Оживляем загадочный домофон с резистивным ключом

Приветствую всех!

Обычно, когда я рассказываю про тот или иной домофон, я стараюсь найти максимум информации о нём: от истории его создания до руководства пользователя или даже схем. Но только не в этом случае. Всё, что известно про данный экземпляр, это то, что устанавливался он в Москве в количестве больше одного.

Спустя несколько лет поисков я таки смог найти в коллекцию такой девайс. И, как оказалось, он был намного сложнее, чем я мог себе представить...

Olimex HoT aims to be lightweight, easier-to-use alternative to Home Assistant

Olimex HoT (Home of Things) is a lightweight Smart Home solution designed to run on low-end hardware (128MB RAM, 128MB flash) and interface with nodes running ESPHome. It can serve as an easier-to-use alternative for people who don’t need all the bells and whistles provided by powerful home automation frameworks such as Home Assistant or OpenHAB. Home Assistant open-source home automation software is great, but it requires a system with at least 2GB of RAM, and 4GB of RAM is often recommended for most users. There’s also a steep learning curve. This is what Tsvetan Usunov, Olimex CEO, realized last...
