HD404638R - 4-Bit Single-Chip Microcomputer

Download the HD404638R datasheet PDF. This datasheet also covers the HD404639R variant, as both devices belong to the same 4-bit single-chip microcomputer family and are provided as variant models within a single manufacturer datasheet.

Description

The HD404639R Series is a member of the HMCS400-series microcomputers designed to increase program productivity with large-capacity memory.

The HD404639R Series, completely compatible with the HD404639 Series, reduces current dissipation in half and includes a high-speed version.

Features

  • 8,192-word × 10-bit ROM (HD404638R, HD40A4638R).
  • 16,384-word × 10-bit ROM (HD404639R, HD40A4639R, HD407A4639R).
  • 1,152-digit × 4-bit RAM.
  • 61 I/O pins and 7 dedicated input pins  12 high-current output pins: Eight 15-mA sinks (a maximum of 7 pins can be used at the same time) and four 10-mA sources.
  • Four timer/counters.
  • Eight-bit input capture circuit.
  • Three timer outputs (including two PWM outputs).
  • Two event counter inputs.

To all our customers Regarding the change of names mentioned in the document, such as Hitachi Electric and Hitachi XX, to Renesas Technology Corp. The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.) Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand names are mentioned in the document, these names have in fact all been changed to Renesas Technology Corp. Thank you for your understanding.
