Electrical considerations system

E-blocks are built on a bus-based concept 

based on D-type connectors. D-types are 

used because they are rugged and because 

their physical properties allow you to snap 

E-blocks together to form a system which 

mounts onto a backplane. 

Each E-block D-type connector consists 

of 8 bits and ground - 9 connections in 

total. Upstream boards connect using 9 

way D-type sockets (female). Downstream 

devices connect to 

E-blocks using 9 way 

D-type plugs (male). 

This combination 

works remarkably 

well as most system 

topologies require 

upstream devices to 

connect directly to 

downstream ones. 

On each D-type connector bit 0 is on pin 

1, bit 1 is on pin 2, etc. Pin 9 is designated 

0V.   Where two upstream devices need to 

be connected together a gender changer 

or Insulation Displacement Connector (IDC) 

cable with two IDC sockets on can be used.

Adding power

Power is routed separately between E-blocks 

using simple screw terminals and stripped 

wires. This facilitates the interpretation 

of E-blocks with different voltage levels 

(notably 3.3V and 5V). Most downstream 

E-blocks are compatible with 3.3V. All 

upstream E-blocks have power outputs 

on screw terminal connectors. Upstream 

E-blocks are powered by applying a higher 

voltage via a power jack connector and use 

a regulator to generate power for other 

E-blocks in the system.  As 0V is connected 

to all blocks through the 9 way D-type 

connectors, it is only necessary to connect 

+V to all E-blocks - ground connects via 

the D-type. To neaten up more permanent 

systems power wires can be looped under 

E-blocks and under the backplanes.

 

Using ZIF sockets

It is possible to use Zero Insertion 

Force (ZIF) sockets with those 

upstream boards with DIL 

sockets. ZIF sockets are 

useful where the chips will 

be removed from the 

programmer many 

times. Some E-blocks 

boards may have 

other components 

close to the DIL 

socket in question. 

If this is the case 

then you can simply insert 

additional DIL sockets to gain 

enough height so that the ZIF socket can be 

satisfactorily inserted.

Circuit diagrams

Each E-blocks board has an accompanying 

technical datasheet. In the datasheet you 

will find a complete description of the 

hardware, test instructions, and a full circuit 

diagram with a description. For many 

boards you will also find sample code, 

coding instructions, and application notes. 

Datasheets are available on our website:
