Allwinner A523 octa-core Cortex-A55 processor to show up in tablets, SBCs

Allwinner A523 is an octa-core Cortex-A55 processor clocked at up to 1.4/1.8GHz in big.LITTLE (DynamIQ) configuration and mainly designed for tablets with multiple display interfaces such as two 4-lane MIPI DSPI interfaces, two MIPI CSI camera interfaces, a Mali-G57 GPU, and more. But the block diagram below also shows two Gigabit Ethernet (GMAC) interfaces and HDMI 2.0 output among other interfaces meaning it will likely be used in Smart Home products as the Allwinner R828/MR828, and possibly automotive products as the Allwinner T527. I first discovered the Allwinner A523 last March via a tweet by 柚木鉉 (GLGH_), but there was little information at that time. We now have further details about the processor and upcoming products such as the Teclast P26T, and a potential Allwinner A523 single board computer or module. Allwinner A523 preliminary specifications: CPU Application – Octa-core Arm Cortex-A55 @ in big.LITTLE configuration with four cores @ […]

Micro RP2040 is a tiny Raspberry Pi RP2040 module with a USB Type-C port, 28 castellated & through holes

SB Components’ Micro RP2040 is a tiny module based on the Raspberry Pi RP2040 Arm microcontroller with up to 23 GPIOs and a USB Type-C port for easy powering and programming. Ever since the Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller was released, companies have been making tiny modules based on it. Some come with a USB Type-C port such as the Pimoroni Tiny 2040 and the Adafruit QT Py RP2040 boards, while others focused on providing a smaller form factor for soldering only with design such as the RP2040 Stamp or the minuscule 12x12mm Femto module. The Micro RP2040 module comes with a USB-C port and more I/Os than competing modules thanks to a slightly larger 25 x 24.95mm design. Micro RP2040 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 MHz with 264kB of SRAM Storage – 2MB QSPI flash USB – USB Type-C […]

Fudan Micro JFM7K325T is a clone of AMD Embedded Kintex 7 325T FPGA

Shanghai Fudan Microelectronics Group, also known as FMSH, has designed a clone of the AMD Embedded (previously Xilinx) Kintex 7 325T FPGA found in some boards and modules in mainland China. We are used to seeing clones or fakes of the STM32 microcontrollers, but somebody called “whatever” on Twitter noted a full-featured board based on a clone of the Kintex-7 325T FPGA with 326,080 LUTS and 16 transceivers. Twitter users were quick to point out the board was based on Fudan Micro JFM7K325T, and that it was indeed a clone of the Kintex 7 325T FPGA. The company describes itself as a “domestic leading company specializing in the design, development, production (testing), and system solution provision of super-large-scale integration”, but the company’s website does not have any information about the JFM7K325T chip. I could not find the board above online, but I still found MagicChips’ MC-JFM7K325T core board based on […]

MangoPi mCore-R818 module powers CyberPad 3.1-inch handheld android “tablet”

mCore-R818 is the first time that MangoPi adopts the design combination of a core-lite module and a carrier board. As its name suggests, it is an AllWinner R818 SoM whose SoC integrates an Imagination PowerVR GE8300 GPU for UI rendering, can drive MIPI DSI, LVDS, and RGB displays, as well as cameras through a MIPI CSI interface, 8MP/5MP/2MP interfaces. The Allwinner R818 system-on-module powers a feature-rich carrier board as well as an upcoming Cyberpad Android “tablet” with a 3.1-inch display. MangoPi mCore-R818 The package design of the processor itself is small, so the MCore-R818 core board is only 3x3cm in size, but still contains four components with the Allwinner R818, the eMMC flash, LPDDR4 memory, and the AXP717 PMU. MangoPi provides two hardware configurations: 2GB DDR with 16GB eMMC flash, and 4GB DDR with 32GB eMMC flash. MCore-R818 Core Lite Specifications: SoC – Allwinner R818 CPU – Quad-core Arm Cortex-A53 […]
