Notes to Table 1–1:
(1) The EP2C15A is only available with the Fast On feature, which offers a faster POR time. This device is available in
both commercial and industrial grade.
(2) The EP2C5, EP2C8, and EP2C20 optionally support the Fast On feature, which is designated with an “A” in the
device ordering code. The EP2C5A is only available in the automotive speed grade. The EP2C8A and EP2C20A
devices are only available in industrial grade.
(3) This is the total number of 18 × 18 multipliers. For the total number of 9 × 9 multipliers per device, multiply the
total number of 18 × 18 multipliers by 2.
