MC9RS08KA8 Series
Covers: MC9RS08KA8
MC9RS08KA4
Features:
• 8-Bit RS08 Central Processor Unit (CPU)
– Up to 20 MHz CPU at 1.8 V to 5.5 V across temperature
range of –40°C to 85°C
– Subset of HC08 instruction set with added BGND
instruction
• On-Chip Memory

voltage and temperature; KA4 has 4 KB flash
– 254 byte random-access memory (RAM); KA4 has 126
byte RAM
– Security circuitry to prevent unauthorized access to
RAM and flash contents
• Power-Saving Modes
– Wait and stop

Electrical Characteristics
Introduction
This chapter contains electrical and timing specifications for the MC9RS08KA8 series of microcontrollers
available at the time of publication.
3.2
Parameter Classification
The electrical parameters shown in this supplement are guaranteed by various methods. To give the
customer a better understanding the following classification is used and the parameters are tagged
accordingly in the tables where appropriate:
Table 2. Parameter Classifications
P
C
Those parameters are guaranteed during production testing on each individual device.
Those parameters are achieved by the design characterization by measuring a statistically relevant
sample size across process variations.
Those parameters are achieved by design characterization on a small sample size from typical devices
under typical conditions unless otherwise noted. All values shown in the typical column are within this
category.
Those parameters are derived mainly from simulations.
T
D
NOTE
The classification is shown in the column labeled “C” in the parameter
tables where appropriate.
