DIFFERENCES BETWEEN THE IDT72V255LA/72V265LA AND IDT72V255L/72V265L
IDT has improved the performance of the IDT72V255/72V265 SuperSync FIFOs. The new versions are designated by the “LA” mark. The LA part
is pin-for-pin compatible with the original “L” version. Some difference exist between the two versions. The following table details these differences.

First Word Latency
60ns(2) + tREF + 1 TRCLK(4)
tFWL
1 = 10*Tf
(3) + 2TRCLK(4)(ns)
First word latency in the LA part is
(IDT Standard Mode)
a fixed value, independent of the
frequency of RCLK or WCLK.
First Word Latency
60ns(2) + tREF + 2 TRCLK(4)
tFWL
2 = 10*Tf
(3) + 3TRCLK(4)(ns)
First word latency in the LA part is
(FWFT Mode)
a fixed value, independent of the
frequency of RCLK or WCLK.
Retransmit Latency
60ns(2) + tREF + 1 TRCLK(4)
tRTF
1 = 14*Tf
(3) + 3TRCLK(4)(ns)
Retransmit latency in the LA part is
(IDT Standard Mode)
a fixed value, independent of the
frequency of RCLK or WCLK.
Retransmit Latency
60ns(2) + tREF + 2 TRCLK(4)
tRTF
2 = 14*Tf
(3) + 4TRCLK(4)(ns)
Retransmit latency in the LA part is
(FWFT Mode)
a fixed value, independent of the
frequency of RCLK or WCLK.

NOTES:
1. WCLK and RCLK can vary independently and can be stopped. There is no restriction on operating WCLK and RCLK.
2. This is tSKEW3.
3. Tf is the period of the ‘selected clock’.
4. TRCLK is the cycle period of the read clock.
5. Typical ICC1 is based on VCC = 3.3V, tA = 25
°C, fS = WCLK frequency = RCLK frequency (in MHz using TTL levels), data switching at fS/2, CL = Capacitive Load (in pF).
