Texas Instruments 4K DLP Chip Should Bring Affordable 4K Projectors to the Home, Office and School

4K Ultra High Definition (UHD) is slowly with the price of 4K television going down, 4K media players flooding the market starting at $40, and 4K content appearing online via services like Netflix and over the air with DVB-S2. Thanks to the latest Texas Instruments DLP 0.67″ digital micromirror device (DMD), a cost down version of the 1.38″ DMD used in around 80% of cinemas worldwide, we could start seeing affordable 4K projectors in the second half of 2016. The chip includes 4 millions tiny mirrors that quickly switch to generate the ~8 millions pixels required by a 3840×2160 display, and should be found in projectors capable of delivering up to 5,000 lumens. The DLP chip can be used in home theaters, but also in the office and at school for presentations or courses were text needs to be easily readable. The solutions should delivery 100″+ displays with sharp images […]

Texas Instruments Introduces Entry level Sitara AM3351 Cortex-A8 Processor

Texas Instruments Sitara AM335x processor are designed by industrial applications, and found in develompent board such as BeagleBone Black or BeagleBone Green, and the company has recently launched the new Sitara AM3351 Cortex A8 processor without 3D GPU, no PRU just like AM3352, but they’ve also canned the two CAN interfaces (sorry, I had to) in order to bring the cost lower, while keeping the processor software and pin-to-pin compatible with other AM335x processors available in 13×13 mm package. TI Sitara AM3351 CPU clock will also be limited to 300 MHz to 600 MHz with respectively AM3351BZCE30 and AM3351BZCE60 parts. It will only come with one Gigabit Ethernet port instead of up to two ports of other members of the family that are produced in 15x15mm package, and temperature range is limited to 0 to 90 C. Other features remain the same, and the processors will support TI-RTOS, Linux, Android, […]

TI SimpleLink CC1310 Wireless MCU Promises 20 Km Range, 20-Year Battery Life on a Coin Cell

Some LPWAN standards such as SigFox, LoRa, or nWave allows for transmission of data at low bitrate over several kilometers, and I’ve very recently featured Microchip’s LoRa modules and motes in this blog. So when Texas Instruments sent their December 2015 newsletter entitled Wireless MCU spans 20 km on a coin cell, I decided to have a look, and the company’s CC1310 wireless Cortex-M3+M0 MCU based on a proprietary sub GHz technology also claims to last 20-year on a coin cell for applications such as grid communication infrastructure and heat and water meters. SimpleLink CC1310 key features: Microcontroller – ARM Cortex-M3 @ up to 48 MHz with up to 128KB programmable flash, 8KB DRAM for cache/general purpose, 20KB Ultralow Leakage SRAM Sensor Controller – Ultralow power and autonomous; 16-Bit Architecture; 2KB of Ultralow Leakage SRAM for code and data RF core Cortex M0 core with 4KB RAM, and ROM Data […]

Texas Instruments Announces Sitara AM437x Cortex A9 SoCs and Evaluation Modules

The first time I heard about Texas Instruments Sitara AM437x was via a TechNexion EDM-CT-AM437x system-on-module back in 2012, but Texas Instruments Sitara Cortex A9 processors development seems to have dragged a little longer than expected. Nevertheless, the company has now formally announced their Sitara AM437x ARM Cortex A9 SoC targeting automation, IoT gateways, and other industrial applications, and featuring four PRUs (Programmable Real-time Units), and support for dual camera for terminals with bar code scanning. At launch there will be four AM437xprocessors: AM4376, AM4377, AM4378, and AM4379. The processors will all be based on a single Cortex A9 core @ 800 to 1000 MHz with 64KB SRAM shared with 32KB data cache and 32KB programmable cache, 256 KB L2 and L3 caches, a 32-bit memory interface supporting LPDDR2, DDR3, and DDR3L, a 2-port Gigabit Ethernet switch , two USB 2.0 OTG + PHY and the following other interfaces: Serial Ports […]
