The first EEPROM that used Fowler-Nordheim tunnelling to erase data was invented by Bernward and patented by Siemens in 1974. [24] In February 1977, Israeli-American Eliyahou Harari at Hughes Aircraft Company patented in the US a modern EEPROM technology, based on Fowler-Nordheim tunnelling through a thin silicon dioxide layer between the floating-gate and the wafer.
Two PIC16C84s on a false smart-card used in the nineties to decode the signals of Sky Television.. The PIC16C84 was introduced in 1993 and has been hailed as the first PIC microcontroller to feature a serial programming algorithm and EEPROM memory (it was preceded by the Motorola MC68HC805B6 and MC68HC805C4 along with the MC68HC11E2 with serial bootloader and EEPROM program storage released in ...
The EFM32 microcontroller family is one of the two products of Energy Micro. The other being EFR4D Draco SoC radios. In April 2008, Energy Micro announced that it licensed the ARM Cortex-M3 core. [21] In October 2009, Energy Micro announced the EFM32 Gecko MCU family (EFM32G series) based on Cortex-M3. [22]
PICAXE 20M2. PICAXE is a microcontroller system based on a range of Microchip PIC microcontrollers.PICAXE devices are Microchip PIC devices with pre-programmed firmware that enables bootloading of code directly from a PC, simplifying hobbyist embedded development (not unlike the Arduino and Parallax BASIC Stamp systems).
PIC projects may utilize real-time operating systems such as FreeRTOS, AVIX RTOS, uRTOS, Salvo RTOS or other similar libraries for task scheduling and prioritization. An open source project by Serge Vakulenko adapts 2.11BSD to the PIC32 architecture, under the name RetroBSD. This brings a familiar Unix-like operating system, including an ...
The 68HC11 [1] (also abbreviated as 6811 or HC11) is an 8-bit microcontroller family introduced by Motorola Semiconductor in 1984 (later from Freescale then NXP). [2] [3] It descended from the Motorola 6800 microprocessor by way of the 6801.
Netduino – microcontroller board, .NET Micro Framework based; NodeMCU – Wi-Fi microcontroller board; Novena – an ARM based computer built by Andrew Huang and associates; OpenPOWER – Power ISA, an open-source hardware instruction set architecture initiated by IBM; OpenSPARC – Sun's, later Oracle's high-performance processor
The RL78 family is an accumulator-based register-bank CISC instruction set architecture (ISA). [2] Although it has eight 8-bit registers or four 16-bit register pairs, essentially all arithmetic operations are performed on a single accumulator (the A register or AX register pair).
