The TS-7400 is a small embedded Single Board Computer (SBC) that is designed to provide extreme performance for applications which
demand high reliability, fast bootup/startup, and connectivity at low cost and low power, such as point-of-sales (PoS), vending machines,
data acquisition units, data recorder modules, etc. Additional TS-7400 specifications include:
- 100% soldered-on components
- Fanless -40° to +70°C with CPU 200MHz
- Up to +85°C with CPU speed under 166MHz
- Board dimensions are 2.9" x 4.7"
- Power requirements are 5V DC @ 350mA
- Standard RoHS Compliant
The TS-7400 enables more control and access to the EP9302's core peripherals. The 40-pin header provides 3 TTL-level serial
ports, 20 bidirectional schmitt-triggered GPIO pins, digital audio codec via the AC97/I2S interfaces, 4 12-bit 0-3.3V analog input (ADC) pins,
and a high-speed (up to 14.7MHz) dedicated SPI bus. Also, a simple 8-bit multiplexed general purpose parallel bus implemented in the on-board
CPLD is available via GPIO pins 0-13. The 26-pin header brings out other interfaces such as JTAG, USB, special lines for the TS-9441,
and 1.8V/3.3V/5V power supply.
All the serial ports on the TS-7400 are TTL-level only, meaning that there are no RS-232 or RS-485 driver chips
(these must be added externally). The TS-7400 supports tx-enable output for RS-485 on one serial port though.
The TS-7400 boots to NAND flash using a proprietary bootloader optimized for speed. The hardware accelerated
NAND flash controller is a unique feature implemented in the on-board CPLD that provides hardware ECC, allowing the system to bootup to a
Linux shell prompt in about 1.1 seconds. The on-board CPLD can be also used to provide custom functionality through an extra core,
such as additional COM ports, quadrature channels, PWM, timers, frequency counters, etc. Contact embeddedTS for custom design services.
Two user controlled red and green LEDs are available and stacked vertically on the board. The TS-7400 engine
is a standard size that fits into some off-the-shelf extruded aluminum cases, such as the Hammond Manufacturing Enclosures.

TS-9441 Production Blast/Test/Recovery Peripheral Board
In order to configure and setup the TS-7400 flash system during development, a TS-9441 peripheral board is
required. The TS-9441 has 2KB EEPROM, and 2MB serial flash, so it
can be used to bring-up/recover "dead" TS-7400 boards. Using a console on the TS-7400 is only possible through the TS-9441 RS-232
serial port, named Console Header. Also, the TS-9441 enables regulated 5V DC power in. Once the TS-7400 is configured and loaded, it can safely
The TS-7400 single board computer boots to Linux from NAND flash using the proprietary TS-FLASHBOOT bootup firmware residing in ROM memory. It can also boot from an SD card, through the TS-SDBOOT firmware.
The TS-7400 Ultra-Fast bootup solution was optimized for speed and includes kernel, initrd, and filesystem
(Busybox) tweaks. The bootstrap
setup is very similar to the 1.69 second
Fast Bootup for TS-7300,
but is almost 30% faster. In addition,
the hardware accelerated NAND
flash controller is a unique
feature implemented in the on-board
CPLD that provides hardware ECC,
allowing the system to skip software
ECC during startup and enabling
boot to a Linux prompt
in 1.1 seconds. Since the TS-7400
actually boots to an initrd with
a read-only mounted filesystem,
it is possible to have something
other than a shell prompt running
after bootup by editing the /linuxrc
shell script on the initrd. Additional TS-7400 software features include:
- Boots Linux out-of-the-box in 1.10 seconds (to shell prompt).
- Flexible booting options (SD card, NAND flash or offboard SPI flash).
- SD card pre-installed with standard Debian Linux distribution.
- Firmware has ability to verify boot medium CRC before allowing bootup.
- Ability to boot password-locked SD cards.
- Startup Linux miniroot scripts allow flexible root and backup
filesystem selection (SD, flash, NFS, USB flash) as well as
software field upgrade support.
- Linux "bootload" program
allows booting of Linux kernels and
other Operating Systems from within Linux itself.
The TS-7400 Arm®-based SBC is compatible with a wide range of Operating Systems (OS's). The Linux choice is highly recommended and our
products are totally integrated with the open-source vision. The Linux OS, TS-Kernel 2.4.26, is shipped by default with our Arm-based SBCs and includes
complete driver support for our hardware within the kernel, enabling quick time to market for end-users' applications. Examples and source codes
are also available for downloading.
The Arm®-based SBCs include the TS-Linux compact embedded OS installed by default in on-board flash memory (8MB, JFFS or YAFFS filesystems).
The eCos/Redboot boot loader is used to open the OS of choice. In addition, the full featured Debian Linux distribution can be used with a network
directory (NFS root) or larger flash drives (256MB), such as Compact Flash, SD cards or USB memory sticks. The Linux system includes a complete
GNU C/C++ embedded development environment installed. In addition, Apache Web Server, FTP, SSH, Telnet and Samba internet services
are available with C/PHP/Perl for embedded CGI development.
The Linux solution is compatible with the RTAI real-time extension, enabling systems with strict timing requirements to be handled
with our SBCs. Furthermore, NetBSD has been ported to the TS-7400 and Java solutions are also available.
