Table 1.1: J-Link ARM specifications
The following table lists performance values (Kbytes/s) for writing to memory (RAM):
Table 1.2: Download speed differences between hardware revisions
All tests have been performed in the testing environment which is described on Mea-
suring download speed on page 206.
The actual speed depends on various factors, such as JTAG/SWD, clock speed, host
CPU core etc.

J-Link Rev. 6 — 8
Uses a 32-bit RISC CPU.
Maximum download speed (using DCC) is over 700 Kbytes/second.
JTAG speed: Maximum JTAG frequency is 12 MHz; possible JTAG speeds are:
48 MHz / n, where n is 4, 5, ..., resulting in speeds of:
12.000 MHz (n = 4)
9.600 MHz (n = 5)
8.000 MHz (n = 6)
6.857 MHz (n = 7)
6.000 MHz (n = 8)
