Technical Data
Freescale Semiconductor, Inc.
This addendum provides additional information to the
MC68HC908JB8 Technical Data, Rev. 2
(Motorola document number MC68HC908JB8/D),
MC68HC08JB8A
The MC68HC08JB8A is the ROM part equivalent to the MC68HC908JB8. The
entire MC68HC908JB8 data book apply to this ROM device, with exceptions
outlined in this addendum.

1. VDD = 4.0 to 5.5 Vdc, VSS = 0 Vdc, TA = TL to TH, unless otherwise noted.
2. Typical values reflect average measurements at midpoint of voltage range, 25 °C only.
3. Run (operating) IDD measured using external square wave clock source (fXCLK = 6 MHz). All inputs 0.2 V from rail. No dc
loads. Less than 100 pF on all outputs. CL = 20 pF on OSC2. All ports configured as inputs. OSC2 capacitance linearly
affects run IDD. Measured with all modules enabled.
4. Wait IDD measured using external square wave clock source (fXCLK = 6 MHz); all inputs 0.2 V from rail; no dc loads; less
than 100 pF on all outputs. CL = 20 pF on OSC2; 15 kΩ ± 5% termination resistors on D+ and D– pins; all ports configured
as inputs; OSC2 capacitance linearly affects wait IDD
5. STOP IDD measured with USB in suspend mode; OSC1 grounded; transceiver pullup resistor of 1.5 kΩ ± 5% between VREG
and D– pins and 15 kΩ ± 5% termination resistor on D+ pin; no port pins sourcing current.
6. Maximum is highest voltage that POR is guaranteed.
7. If minimum VREG is not reached before the internal POR reset is released, RST must be driven low externally until minimum
VREG is reached.
8. The numbers in parenthesis are MC68HC08JB8 (non-A part) values.
