Flash emulation of ROM versions
– ROM versions 3S12HZ256, 3S12HZ192, 3S12HZ128 and 3S12HN128 should use the
9S12HZ256 for Flash emulation.
– ROM versions 3S12HZ64, 3S12HN64, 3S12HZ32 and 3S12HN32 should use the 9S12HZ64
for Flash emulation.
Pin out explanations:
– A/D is the number of A/D channels.
– PWM is the number of TIM channels.
– LCD denotes the number of front planes times the number of back planes.
– Motor denotes the number of high current drive pins / number of stepper motors which can be
driven
– SSD denotes whether this device features a Stepper Stall Detection Circuit
– Versions with one SCI will use SCI0
– Versions with one CAN will use CAN0
– I/O is the sum of ports capable to act as digital input or output.
144 Pin Package:
Port A = 8, B = 8, E = 6 + 2 input only, H = 8, J = 4, K = 5, L = 8, M = 6, P = 6, S = 8, T = 8, U
= 8, V = 8, W = 8, PAD = 16 input only.
14 inputs provide Interrupt capability (H = 8, J = 4, IRQ, XIRQ).
112 Pin Package for H Versions:
Port A = 8, B = 8, E = 6 + 2 input only, K = 5, L = 4, M = 4, P = 2, S = 6, T = 8, U = 8, V = 8, W
= 8, PAD = 8 input only.
