Interfaces

3.1.1

ISSP

In-System Serial Programming (ISSP) is a Cypress legacy interface used to program the PSoC 1

family of microcontrollers. MiniProg3 supports programming PSoC 1 devices through the 5-pin

connector only.

For more information about the ISSP interface, see the PSoC 1 Technical Reference Manual.

3.1.2

JTAG

The Joint Test Action Group (JTAG) standard interface is supported by many high-end

microcontrollers, including the PSoC 3, PSoC 5LP, and PSoC 6 families. This interface allows a

daisy chain bus of multiple JTAG devices. The MiniProg3 supports programming and debugging the

PSoC 3, PSoC 5LP, and PSoC 6 devices using JTAG, through the 10-pin connector only.

3.1.3

SWD/SWV

Recent ARM-based devices have introduced a new serial debugging standard called Serial Wire

Debug (SWD). The PSoC 3, PSoC 4, PSoC 5LP, and PSoC 6 device families implement this

standard, which offers the same programming and debugging functions as JTAG except the

boundary scan and daisy chain. SWD uses fewer pins of the device than the JTAG. MiniProg3

supports programming and debugging of PSoC 3, PSoC 4, PSoC 5LP, and PSoC 6 devices, using

SWD through the 5-pin or 10-pin connector.

The Single Wire Viewer (SWV) interface, also introduced by ARM, is used for program and data

monitoring, where the firmware may output data in a method similar to "printf" debugging on PCs,

using a single pin. MiniProg3 supports monitoring of PSoC 3 and PSoC 5LP firmware, using SWV,

through the 10-pin connector and in conjunction with SWD only.

The PSoC 3, PSoC 4, PSoC 5LP, and PSoC 6 devices support the SWD programming through the

SWD lines. Before programming a PSoC 3, PSoC 4, PSoC 5LP, or PSoC 6 device, make sure you

review the electrical connection requirements in the respective device datasheet or in the PSoC 3,

PSoC 4, PSoC 5LP, and PSoC 6 device programming specifications. You can find the datasheets

and programming specifications here:

3.1.4

A common serial interface standard is the I

microcontrollers and other ICs on the same board, but can also be used for intersystem

communications. MiniProg3 uses an I

data with I

C-enabled devices on the target board. For example, this feature may be used to tune

the CapSense

When MiniProg3 is configured in the I

on the SDA and SCL lines.
