Sprintek's Released New USB, HID over I2C and SMBus Interfaced FlexMatrix™ Keyboard Encoder ICs

Ultra-Low Power Low Cost FlexMatrix™ Keyboard Encoders with 8x20 Keyboard Scan, 1 PWM Backlight and 4 LEDs Control, Field-Upgradable Bootloader - SK5212 (USB), SK5222 (HID over I2C), SK5223 (SMBus)
SIMI VALLEY, Calif. - Sept. 2, 2020 - PRLog -- Sprintek Corp., a leading supplier of high-quality microcontroller-based semiconductor products for computers peripherals, medical device and industrial applications, today announced availability of FlexMatrix™ Keyboard Encoder SK5212 (USB), SK5222 (HID over I2C), SK5223 (SMBus), three fully programmable keyboard encoder ICs that provides developers with an elegant solution to encode any keyboard. The encoder IC can be programmed by the user to scan any keyboard matrix of up to 8 rows and 20 columns.

The SK5212/SK5222/SK5223 provides one key-controlled and command-controlled PWM for backlight LED PWM brightness control. An IO pin BLEN can be used to turn off the backlight circuit totally.

The SK5222 (HID over I2C) and SK5223 (SMBus) are power efficient with power consumption @ 3V: 0.1uA (no key pressed) 110uA (1 key) 50uA (inc per Key), and 6.5x4.5x0.9mm 46-pin QFN small package . It is ideally suited to battery powered consumer products such as laptop PC's built-in keyboard, peripheral keyboards of tablet PCs, mobile phone and wireless keyboard.

The SK5212 (USB) is also power efficient with power consumption 5.8mA (operation), 300uA (suspend) with LQFP package and its custom matrix definition. It is ideally suited to PC or tablet's external keyboard, industrial applications like POS, industrial keyboards.

The FlexMatrix™ keyboard encoders expedite time-to-market by making keyboard development simpler, faster and more flexible. The FlexMatrix™ products offer the features of a whole series of standard and custom encoders in a single part, thereby lowering a developer's engineering resource commitment and total solution cost.

Key Features of the FlexMatrix™ SK5212/SK5222/SK5223:

-- Low Speed USB 2.0 (SK5212), HID over I2C v1.0 (SK5222), SMBus v.10 (SK5223)
-- 8 x 20 keyboard scan
-- 1 PWM backlight brightness control by Key/Command controlled
-- Matrix Table for Fn, FnLock, and NumLock On/Off cases
-- KeyLock for undetachable washable design
-- User-programmable matrix for universal applicability
-- Deferred definition allows design revision after hardware assembly
-- Bootloader for field firmware upgrade
-- Built-in power management minimizes power consumption.
-- Automatic discard of "phantom" or "ghost" key presses
-- No external crystal and EEPROM are needed
-- Macro keys that can combine key output with special functions.
