  • As other tablets like the Motorola Xoom and the Apple iPad 2 have made their mark in the consumer electronics market, many have waited with anticipation to see what Canadian smartphone company Research-In-Motion (RIM) would respond with. At one time RIM was the unprecedented leader in smartphones, with their Blackberry line controlling almost the smartphone market share. Over time, RIM has seen its dominance dwindle because of companies like Apple and Motorola. It should come as no surprise then that RIM was quick to announce their contribution to the burgeoning tablet market with the introduction of the RIM Blackberry Playbook.

    With much speculation as to when the Playbook would finally be released, RIM announced the launch date officially as April 19th, 2011. This 7-inch tablet also displays the fruits of RIM’s latest acquisition, QNX as the Playbook is the first to feature a new operating system called Tablet OS, optimized for the Playbook. This OS also supports Android applications - which open up the Playbook to a huge library of software.

    Early reviews for the Playbook have been lukewarm based on some expectations with the OS but how does the hardware hold up? Our teardown of the RIM Blackberry Playbook will provide a better idea of how the technology compares to recent releases like the iPad 2, the Xoom and Samsung Galaxy Tab.

    Once we opened up the Blackberry Playbook (which was no easy task due to a very rigidly built tablet), we immediately recognized that Texas Instruments would be the major design winner. The biggest of the design wins came in the form of the selection of the OMAP4430 to be the Playbook’s applications processor. To coincide with the selection of the OMAP4430, RIM has seemingly decided to stay with the OMAP 4 platform by selecting key components like the TWL6040 power management IC and the PS63020 high efficiency single inductor buck-boost converter.

    Another MAJOR design win for TI and one that had our resident RF experts excited was the discovery of the Texas Instruments WL1283C WiLink 7.0 single-chip WLAN, GPS, Bluetooth and FM solution. This is the first time we’ve seen a four-in-one radio IC in use in a consumer application product and the decision to utilize this in the Playbook shows that RIM was willing to make daring decision designs.

    Primary Component Listing: 

    • SanDisk-Toshiba SDIN5C2-16G - MLC NAND Flash Memory - 16 GB
    • Elpida B8064B2BPB - 1 GB LPDDR2 DRAM system memory located on the OMAP4430
    • Texas Instruments OMAP4430 - Applications processor located in package-on-package on board.
    • Texas Instruments TWL6030 - Power management IC
    • Intersil i951 9HRTZ F032RG - IC
    • Wolfson Micro WM8994E - Audio Codec
    • ST Microelectronics XTV0987 - 5 MP Mobile Image Processor (found in Blackberry Torch)
    • Texas Instruments WL1283C - WiLink 7.0 single-chip WLAN, GPS, Bluetooth 4.0 and FM solution
    • Invensense MPU-3050 - Triple Axis (X/Y/Z) MEMS Gyroscope (Motion Processing Unit) - SIX AXIS sensor
    • Cypress CY8CTMA3 - touch screen controller
    • Bosch BMA150 – Digital accelerometer
    • Texas Instruments LMV339 – General-purpose low-voltage comparator
    • Intersil ISL9519 - Narrow VDC regulator/charger with SMBus interface

    Taking a closer look at the OMAP4430

    We haven’t had a chance to do a full analysis of the OMAP4430 package-on-package (which features Elpida Low Power DDR2 DRAM) found in the Playbook just yet - though we’ll be done soon enough, we have had the opportunity to delve into the OMAP4430 in a standalone IC we analyzed earlier. Here are some of our findings but more information can be found in our Functional Layout of the Texas Instruments 45nm OMAP4430 Applications Processor report that is available now.

    The OMAP4430 is the latest from the OMAP family of application processors by TI, manufactured at 45-nm CMOS process, the OMAP4430 features two cores based on the dual-core Cortex-A9 MP Core general purpose processors and features a clock speed of 1 GHz. Below are some images that we’ve taken from our early analysis of the standalone OMAP4430
