8 / 752 page Notes on S-Mask Model (Single-Power-Supply Specification) There are two versions of the H8/3437F with on-chip flash memory: a dual-power-supply version and a single-power-supply (S-mask) version. Points to be noted when using the H8/3437F single- power-supply S-mask model are given below. 1. Notes on Voltage Application 12 V must not be applied to the S-mask model (single-power-supply specification), as this may permanently damage the device. The flash memory programming power supply for the S-mask model (single-power-supply specification) is V CC. The programming power supply for the dual-power-supply model is the FVPP pin (12 V), but the single-power-supply model (S-mask model) does not have an FV PP pin. Also, in boot mode, 12 V has to be applied to the MD 1 pin in the dual-power-supply model, but 12 V application is not necessary in the single-power-supply model (S-mask model). The maximum rating of the MD 1 pin is VCC +0.3 V. Applying a voltage in excess of the maximum rating will permanently damage the device. Do not select the HN28F101 programmer setting for the S-mask model (single-power-supply specification). If this setting is made by mistake, 12 V will be applied to the STBY pin, possibly causing permanent damage to the device. When using a PROM programmer to program the on-chip flash memory in the S-mask model (single-power-supply specification), use a PROM programmer that supports Hitachi microcomputer devices with 64-kbyte on-chip flash memory. Also, only use the specified socket adapter. Using the wrong PROM programmer or socket adapter may damage the device. The following PROM programmers support the S-mask model (single-power-supply specification). DATA I/O: UNISITE, 2900, 3900, etc. Minato: 1892, 1891, 1890, etc. |
