LispDeck handheld lisp computer Runs uLisp on Teensy 4.1 with Wi-Fi, LoRa, and two screens

LispDeck handheld cyberdeck

Designed by Hartmut Graw, the LispDeck is a Handheld Lisp computer built around the Teensy 4.1 microcontroller for Lisp programming on the go. It features a dual-screen setup with a 5-inch touchscreen and, a secondary ST77350-based TFT display. It also has an Adafruit RFM96 radio module, an ESP8266 Wi-Fi module, a rotary encoder, an SD card for storage, and a detachable wireless USB keyboard, all housed in a 3D-printed case. Running the uLisp language, it features a standalone Lisp programming environment without needing a PC or tablet. It is an evolution of the LispBox, with a portable and battery-powered design, which also maintains compatibility. Unlike Raspberry Pi-based cyberdecks, the LispDeck is designed for complete control over the system without the complexity of Linux. It is useful for Lisp enthusiasts who want a compact, dedicated computing device that’s fully documented. LispDeck Specifications SoC – NXP i.MX RT1062 via Teensy 4.1 board […]

Renesas RA4L1 ultra-low-power MCU family offers 168 µA/MHz operation, dual-bank flash, capacitive touch

Renesas RA4L1 ultra low power MCU family

Renesas has recently introduced the RA4L1 ultra-low-power Arm Cortex-M33 MCU family along with two evaluation/development boards. This new lineup consists of 14 ultra-low-power devices based on an 80 MHz Arm Cortex-M33 processor with TrustZone support and designed for metering, IoT sensing, smart locks, digital cameras, and human-machine interface (HMI) applications. The RA4L1 MCU family offers high power efficiency at 168 µA/MHz while active and a standby current of 1.70 µA while retaining SRAM. Additionally, they support segment LCD, capacitive touch, USB-FS, CAN FD, low-power UART, multiple serial interfaces (SPI, QSPI, I2C, I3C, SSI), ADC, DAC, real-time clock, and security features like the RSIP security engine with TRNG, AES, ECC, and Hash.

STMicro expands the STM32C0 Cortex-M0+ MCU family with STM32C051, STM32C091, and STM32C092 (with CAN FD)

STMicro Nucleo-64 board with STM32C092RC MCU

STMicro first introduced the STM32C0 32-bit Arm Cortex-M0+ MCU family as an 8-bit MCU killer in 2023, followed by the STM32C071 adding USB FS and designed for appliances with graphical user interfaces (GUI). The company has now added three new parts with the STM32C051, STM32C091, and STM32C092. The STM32C051 is similar to the original STM32C031 but adds more storage (64KB vs 32KB) and is offered in packages with up to 48 pins, while the STM32C09x parts offer flash densities up to 256 KB in packages up to 64 pins, and the STM32C092 also gains a CAN FD interface. The STM32C09x parts can be seen as an update to the STM32C071 where more flash memory is needed. That’s 30 new SKUs bringing the total to 55 when different packages and flash memory size/RAM size options are taken into account. The STM32C051 offers the same maximal amount of SRAM as the STM32C031 […]

Nuvoton introduces the first security chip based on OpenTitan open-source silicon Root of Trust

OpenTitan demo board Nuvoton open source security chip

Google has announced the start of the fabrication of a Nuvoton security chip featuring OpenTitan open-source silicon Root of Trust (RoT), the first such production-ready chip. It will soon be available in lowRISC’s Voyager 1 demo board, and later this year in Chromebooks and data centers. We first wrote about OpenTitan open-source Root of Trust (RoT) chips in 2020 as a collaboration between Google, Seagate, Nuvoton, Western Digital, lowRISC, as well as some other companies, projects, and universities that aimed at “building a transparent, high-quality reference design and integration guidelines for silicon root of trust (RoT) chips”.  OpenTitan itself reached commercial availability last year, after the first engineering samples were released in 2023, and Google now says the Nuvoton chip (yet to have a proper name) is the first production-ready OpenTitan chip. Hardware Root of Trust (RoT) are small secure microcontrollers that are the equivalent of Certificate Authorities (CAs) to […]
